Explain how three processes unique meiosis generate a great deal of genetic variation.

Expert Solution

Three unique processes that occur during meiosis and which are responsible for generation of genetic variations are;

1. Crossing over; In this process non sister chromatids of homologous chromosomes exchange their parts. It creates new combination of genes which in turn can generate variations.

2. Independent assortment: In metaphase each homolgous pair of chromosome assorts or aligns independently of the other pair of homologous chromosome. Therefore maternal and paternal chromosomes are assorted indepndently into gametes. Thus a gamete randomly receives paternal and maternal chromosomes.

3. Random fertilization of male and female gamete which creates additional variations.

All these unique processes bring up variations .

Meiosis is a process that can generate nearly infinite variation from a single source of genes,...

Meiosis is a process that can generate nearly infinite variation from a single source of genes, even before the additional diversity created by fertilization. There are two main processes that occur during meiosis to generate diversity. Describe each of these processes, referencing where in the meiotic cycle they occur and how they contribute to genetic diversity in the gametes. Format your answer into parts (i) and (ii) for the two processes.

What are two ways that the mechanisms of meiosis introduce genetic variation into the processes of sexual reproduction?
