Yes genetic variation is important in sexually reproducing species.
Sexual reproduction promotes genetic variation by making different combination of gene. Crossing over and independent assortment in chromosom in meiosis resulting in genetic variation. It is also important for speeding up of evolution with more number of individuals adapted to the habitat.

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?

1) If a population stopped reproducing sexually (but still reproduced asexually), how would its genetic variation be affected over time? Explain. 2) A locus that affects susceptibility to a degenerative brain disease has two alleles, A and a. In a population, 16 people have genotype AA, 92 have genotype Aa, and 12 have genotype aa. Is this population evolving? Explain. 3) Explain why natural selection is the only evolutionary mechanism that consistently leads to adaptive evolution.

a) Why do species that reproduce sexually have more genetic variation than species that reproduce asexually? b) Why is it difficult to use genetics to predict exactly how tall someone will be? c) Many prokaryotes reproduce asexually using binary fission. Why is it impossible for a prokaryote to use the process of meiosis for reproduction? d) Monosomy is a genetic disorder. In this disorder, a person receives one gamete that has is missing a chromosome. This gives the person one...
