Offspring

homozygous dominant, while the other is homozygous recessive), and the offspring is heterozygous. The phenotype of both parents are present in the offspring. An example of codominance is if a white flower (rr) and a red flower (RR) breed to produce an offspring (Rr), whose phenotype is red and white stripes, therefore showing that both parents’ phenotype is present. Incomplete dominance is also between true breeding, and the offspring is once again, heterozygous. The phenotype however, is a bend…

Primate parenting is similar to human parenting in a way. They care for their offspring by investing a lot of time and energy into each one of their offspring in order for their young to survive longer. They teach them how to eat, what to eat and how to conform to and behave in the society they live in. A reason as to why they are able to do all of this is because primates are very smart due to their large brains. It has been proven that they are much smarter than other animals. Primate…

The readings for week 14 have provided me with a better understanding of caregiving-related foundational information within current literature. Much of the information that was mentioned was new to me, however there were also key concepts that made sense. The findings for the article by Birditt, Fingerman, and Zarit (2010) especially captured my attention. It is apparent that parents’ feelings about their children is complex and must take multiple factors into consideration. I never thought to…

is a process resulting from variation in heritable traits. A mindless mechanism with no objective, natural selection does not provide organisms with what they need, but instead selects for traits that allow an organism to produce the most viable offspring in a given environment. (Reece) All species arise from a pre-existing species. Cladogenesis…

Anthropologists began to study infanticide more closely when they began to file more cases of intraspecific killings. Primarily, primates engage in infanticide as a reproductive strategy. Male primates can increase their reproductive chances by killing off offspring that were fathered by other males. After a female primate loses an infant, she is no longer in estrus. Estrus, in female mammals, is the time period when female primates are more likely to conceive, and it correlates with ovulation…

males that engage in intrasexual competition, and females that exercise intersexual choice. This is apparent in the morphological and behavioural differences between the sexes. Trivers (1972) argues that this is so due to differential investment in offspring between the sexes, which makes access to females a limiting resource in males' reproductive success. In other words, males compete, females choose. In this essay, I shall critically discuss the evidence that this pattern exists in humans. In…

in the wilderness. The four things that Darwin identified that must be present in order for natural selection to occur are genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction. This activity demonstrated all these factors except genetic variation. For over production of offspring, the beans’ populations were multiplied by three after every round. This is because out of all beans, many will not survive the round, and so more beans…

dark some were light skinned and could pass for white. As slaves women began to give birth to white babies rules and labels were made to ensure that any child born of a slave woman would be a slave. A “mulatto” was the offspring of a white and African. A “quadroon” was the offspring of a…

cells are called our sex cells or gametes which are sperm cells in men and eggs in females. This is how sickle cell is passed on to each generation. If one parent maintains the allele that codes for sickle cell, then there is a possibility their offspring will as well. Meiosis happens in two stages called Meiosis I and meiosis II. Within Meiosis I, there are four phases that occur called prophase I, metaphase I, anaphase I, and telophase I/ cytokinesis. Prophase I takes place when the homologous…

eventually be able to be shot onto another planet. The printer will then print offspring and bacteria to populate that planet. Although there needs to be further advances in Jet propulsion and Genetic Research. Coming back to our offspring, later in the future genetic splicing can make our bones more durable in space. Harvard Medical School has jumped into the idea of the Role of Genetics. The school discussed how genes and offspring will play an enormous part into the exploration and…
