Document Summary

Study guide: biology 1030, test 4: define genetics. What is meant by the following terms: f1 generation?, Fall 2017: two individuals from the f1 generation are then crossed to produce the. What is the difference between an autosome and a sex chromosome. Fall 2017: list and explain the origins of genetic differences among individuals. (there are. 4 that we focused on in class!: crossing-over is a reciprocal exchange of segments of nonsister chromatids during prophase i of meiosis. Crossing-over is part of the reason why two parents can produce offspring with a range of different phenotypes. It is one reason why siblings are not identical to one another (unless they are identical twins): independent assortment of chromosomes results from homologous pairs lining up at random along the metaphase plate during metaphase i of meiosis. The paternal and maternal members of any homologous pair are sorted into gametes independently of any other pair.

Related Questions

1) How does both the environment and genetics influence genetic traits such as phenylketonuria?

2) What is the difference between an autosomal dominant and autosomal recessive pattern of inheritance?

3) How does meiosis help predict the probability of producing gametes and inheriting a trait?

Choose a trait that goes beyond Mendelâs one trait inheritance. Discuss the inheritance (ex. Incomplete dominance, multiple allele, polygenic, pleiotrophy, linkage, environmental influences), the different phenotypes or anything else that deviates from simple genetics. Mendel got lucky with the traits he chose in his pea plants. If he got more complicated traits and inheritance it would have made his findings almost impossible to come to. Talk about how these traits would have made it hard for scientists like Mendel to figure out inheritance the way he did.

Match the following definitions with the correct term. (We have not yet cover all of them in class, but you can find them in your reading.)
