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 …show more content…
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
