Evolutionary Psychology: Dominant Recessive Genes

Superior Essays
List 8:
1. Evolutionary Psychology (p.43): This is a branch of psychology that focuses on how the behavior of people has evolved over time. It specifically focuses on the importance of natural selection or “survival of the fittest”. Our bodies have adapted over time in order to help us do certain behaviors that allow us to survive and reproduce. I found this concept interesting when it mentioned the physical characteristics of both genders today are related to the behaviors that our ancestors needed to perform to survive in the past.
2. Dominant-Recessive Genes (p.50): These kinds of genes allow for two sets of a specific gene in our DNA, but the gene that is expressed and showed in physical characteristics is the “dominant” one. You can have

A teratogen is any substance or agent that can cause a birth defect prenatally. These substances can include hard drugs, incompatible blood types, environmental pollution, diseases, advanced age, stress, and nutritional deficiencies. I will focus more on drug abuse. It is incredibly important for an expecting mother to take care of her body physically and mentally when pregnant in order to have a lower chance of having a child with a birth defect. We can help future mothers gain knowledge about how to care for themselves while they are pregnant and hopefully make an impact on the rates of birth defects caused by teratogens. For this to truly work, we would need to target the mothers at risk of harming their baby through the use of drugs or the unavailability of adequate sustenance. This would most likely be mothers from low income environments, but could also be mothers of high income backgrounds. Another way to prevent teratogen exposure, is to increase the legal repercussions of endangering their unborn …show more content…
These include the dosage of the teratogen, how susceptible the individual is to the teratogen, and the time of prenatal development that the embryo is in while the exposure occurs. Higher dosage has the possibility of more damage and the susceptibility depends on the genes given by the mother and father. We could help certain people avoid substances that are potentially harmful based on their family history. It is also known that males are more susceptible to teratogens than females. The time in development when the embryo or fetus is most vulnerable, is the embryonic period because the embryo has developed more within the placenta, such as organs, and is getting nutrients from its mother via the umbilical cord. By increasing the repercussions of substance abuse for expecting mothers, due to child endangerment, we could hopefully deter soon-to-be mothers to not use drugs during the most critical developmental periods of their child’s life.
It is important for the health of the child in the embryo, but also for the child’s future health and well being. Exposure to teratogens can lead to behavioral, cognitive, and developmental issues later

    A woman who smokes while pregnant is at an incremented risk of experiencing a wide range of birth defects with her newborn child, and she is exposing her pregnancy to many serious risks. Impediments within the pregnancy, caused by the chemicals found in cigarettes, may result in premature labor, miscarriage, or ectopic pregnancy. Smoking while pregnant is precarious because when an expectant mother smokes a cigarette, she imperils the baby to an array of deleterious chemical components. Babies whose mothers smoke during their pregnancies are being put in jeopardy of having a low birth weight, breathing difficulties, and numerous malformations due to the effect chemicals have on them. Tobacco, being the most prevalent substance used in this period, puts innumerable amounts of fetuses and newborns in grave peril.…

    Most people understand that fetuses are extremely fragile and should not be exposed to ionizing radiation; thus, health care providers utilize ultrasound for prenatal imaging. But how safe is ultrasound imaging? Is it safe enough to warrant a fetus’s exposure? Sonography is a safe choice for prenatal imaging, but there are some suspected risks involved. However, the benefits outweigh those risks as long as scans are completed appropriately, especially when it comes to the 3­D and 4­D ultrasounds.…

    Research was done using rats with exposure to toluene to investigate the validity of birth defects. Three groups of rats were exposed to the same level of toluene during mating, gestation, and both. Researchers observed weight reductions in the fetuses that were exposed during the pregnancies. In both mating and gestational groups, skeletal soft tissue deformations were observed (Bowen 2006).…

    1. Is it true that a homozygous dominant father and a homozygous recessive mother could give birth to a homozygous recessive child with the disorder phenotype? Explain. From the information provided, it can be determined that this statement is not true, as the offspring of this couple will not be homozygous recessive for the given trait. As both of the parents are homozygous for their respective alleles, every child would receive an allele from each parent, one being dominant (D) and the other being recessive (d).…

    During the third to ninth week of gestation, teratogens pose that largest risk, causing significant defects, and possibly spontaneous abortion (Bennett, 2015). Although the causative agent is the biggest contributor to the defect, the teratogen may work in concert with the genetic makeup of parents and child. It is recommended that women reduce or eliminate ingestion or contact with teratogens will pregnant, but this is not always possible due to medications for pre-existing…

    Movie Review The film starts by stating that everyday objects, such as toys and foods, can contain toxic chemicals and that there are no restrictions in place for this problem. It follows the life of Edward Brown, who says he is on this journey to learn more about the chemicals found in objects. This journey is motivated by his wife having Crohn's disease and two miscarriages. We are essentially exposed to many harmful chemicals on a daily basis, which is very detrimental to our health. Edward Brown wondered if there was a connection between these chemicals and the miscarriages his wife experienced.…

    In a population there are a number of alleles for a given gene. People who consist of two copies of the same allele is known to be homozygous for only that specific. On the other hand people who consist different alleles are known to be heterozygous to that specific gene. The inheritance patterns will rely on whether the allele is found on an autosomal chromosome or a sex chromosome, and on whether the allele is dominant or recessive.…

    A teratogen is any substance such as a chemical, medication, radiation, virus or infection, etc., that can cause malformation of an embryo. Teratogens can be found anywhere, such as your own home or workplace. It is proven that “teratogens are thought to have the ability to affect the fetus about 10 to14 days after conception” (“Teratogens”, n.d.). The harmful effects are “influenced by fetal genetic vulnerability, type and amount of teratogen, and timing of the exposure during pregnancy”…

    This study pertains to the health of women and embryo, preconception and during pregnancy, when exposed to potentially teratogenic drugs. Stated in the introduction of the study, teratogenic drugs may in fact pose a major threat to the embryo due to its destructive nature in some cases. These drugs are capable of causing abnormal changes to the normal growth of the embryo or fetus, thus leading to improper function and/or structure. At such early stages of growth, these changes are almost always irreversible. In more severe cases, the mother must resort to abortion or a premature birth, which is often associated with mental and/or physical disabilities.…

    1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…

    The effects of environmental influences are wide-ranging depending on the prevailing environmental factors. A particular stage of development fails to take place normally, especially the critical period when cells multiply and enlarge to form organs. Prenatal development is critical in determining the health and structure of a newborn. For example, exposure to chemicals, radioactive material, and drugs among other hazardous conditions may lead to failure in development of some body parts, stunted growth in babies as well as poor cognitive development. Severe exposure can lead to miscarriage or death during and immediately after birth (Hepper 2005).…
