The different kinds of mechanismsthat lead to
Introduction:
Genetic variation refers to the biological systems comprising the populations and the individuals who are different over the space. The gene pool is present that involves different alleles of genes. The genetic variation may occur within or among the populations that are supported by the person who carries the variant genes.

- One of the advantages of sexual reproduction is that it promotes genetic diversity in the offspring. This is because gametes are produced by meiosis, which introduces genetic variation into the resulting gametes. How does meiosis accomplish this? Describe one way (there are several choices) in which meiosis produces new combinations of genes in gametes.arrow_forwardIn what phase of meiosis is chromosome recombination most common?arrow_forwardidentify two main themes underlying the phenomena of chromosomal changes?arrow_forward
