Why is genetic variation generated by meiosis and fertilization important evolutionarily
Homework Answers
Meiosis is important because it ensure that all organisms produced via sexual reproduction contain the correct number of chromosomses. also produces genetic variation by way of the process of recombination. Later , this variation is increased even further when two gamets unite during fertilization , thereby creating offspring with unique combination of DNA.This constant mixing of parental DNA in sexual reproduction helps fuel the incredible diversity of life on earth.

Processes that determine heredity and contribute to genetic variation Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity. Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring always resemble their parents, they are genetically different from both of their...

explain why genetic variation is so important in natural populations, and how it arises and is maintained. explain hardy-weinberg equilibrium as it reltes to the genetic variations and maintenance in populations. include in the explanation: all the equations relating to allele frequencies and genotypic frequencies, and the 5 assumptions.

Why must all sexually reproducing organisms have both mitosis and meiosis in their life cycles? In other words, what is the purpose of meiosis AND what is the purpose of mitosis and how are they different? Without sexual reproduction evolution would be extremely slow. Why ? And what stage and steps in meiosis are so important to the genetic variation within a species?

Random assortment of chromosomes is one of the processes by which genetic variation is generated. Explain what the process means and how new variation is produced as a consequence of random assortment.
