The three main sources of genetic variation arising from sexual reproduction are: Crossing over (in prophase I) Random assortment of chromosomes (in metaphase I) Random fusion of gametes from different parents. What causes genetic diversity? Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation.

The three main sources of genetic variation arising from sexual reproduction are:Crossing over (in prophase I)Random assortment of chromosomes (in metaphase I)Random fusion of gametes from different parents.
In species that reproduce sexually, the behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises in each generation.
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.Jun 7, 2019
Meiosis is the division of the contents of the nucleus that divides the chromosomes among gametes. Variation is introduced during meiosis, as well as when the gametes combine in fertilization.
The genetic diversity has three different sources: mutation, recombination and immigration of genes.May 19, 2021
Three sources of genetic variation are mutation, genetic recombination during sexual reproduction, and lateral gene transfer.
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.Mar 1, 2022
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants.
