Learning Team Reflection: Week Two
Week two focuses on chapters eight, nine, and ten. Chapter eight reviews mitosis and meiosis and how they affect the cell’s life cycle. Chapter nine reviews how chromosomes are inherited and sex-linked genes. Chapter ten reviews DNA’s and RNA’s structure, protein synthesis, and the replication process. Each member in Team A will provide a reflection on what we have learned, any surprises that developed during reading, and any questions that we may still have. Chapter eight provided helpful insight into the process of cell division through sexual and asexual reproduction. The process of meiosis occurs in the reproductive organs of “sexually reproducing …show more content…
136) when two random gametes meet, which helps us understand how there is such genetic variation and diversity within the human species. Toward the end of the chapter, the author’s further discuss this topic by presenting the portion titled The Advantages of Sex. We found what most of us thought to be fact, such as sexual reproduction varies genetics which can help us to adapt to the environment (Simon, Reece, & Dickey, 2010), is actually an unproved hypothesis still driving scientists to research this topic. Our team does not have any questions about the material in the chapter at this …show more content…
Heredity is the transmission of traits from one generation to the next. I find it interesting that only genetic influences are inherited and that any environmental influence during that person's life are not inherited, they die off with the person. Chapter nine also discusses characters and traits of an organism. We learned that our physical traits are called a "phenotype" and that our DNA, or genetic make-up is called a "genotype". I now know that one single gene can be responsible for a disorder. I used to think that disorders were caused by multiple problems and not just one gene. Heterozygotes are two non-matching genes and homozygotes are two identical genes. People and animals have recessive and dominant genes. Parents pass on their genes to their offspring. The easiest way to understand a difference between dominant and recessive genes is by physical appearances. Sex-linked genes are genes that are found on an x or y chromosome and can lead to sex linked
