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 .

Which processes associated with meiosis ensure genetic diversity in offspring? Name two processes that promote variation and explain how they operate.

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?

30. What is the source of genetic variation? How does meiosis contribute to the maintenance of genetic diversity? 31. Describe the preconditions for natural selection to operate and what the results of the natural selection will be. 32. Use the HW equations to solve simple population genetics problems with and without selection. 33. Hardy-Weinberg equilibrium tells us the conditions under which populations will not evolve.

Meiosis Essay Question: Three events in sexual reproduction contribute to genetic variation in a population: independent assortment, crossing over, and random fertilization. Explain how the three processes of sexual reproduction are advantageous to organisms and generate genetic variation within a population. - State which phase of meiosis is occurring during each of the three events. - Also, explain what is happing during these phases that results in the genetic diversity of offspring. - How is this advantageous to the population...
