[Answer] Crossing over resulting in an increase in genetic variation occurs between _____.

Crossing over resulting in an increase in genetic variation occurs between _____.
Crossing over occurs between prophase I and metaphase I and is the process where two homologous non-sister chromatids pair up with each other and exchange different segments of genetic material to form two recombinant chromosome sister chromatids. It can also happen during mitotic division which may result in loss of heterozygosity. Crossing over is essential for the normal segregation of …
Meiosis begins with a diploid cell which contains two copies of each chromosome termed homologs.First the cell undergoes DNA replication so each homolog now consists of two identical sister chromatids.Then each set of homologs pair with each other and exchange genetic information by homologous recombination often leading to physical connections (crossovers) between the homologs.
Crossing over takes place between the chromatids of two homologous chromosomes. Maternal chromatids are red; paternal chromatids are blue. Lines point to the chiasmata ( cross overs ) Crossing over is a basic concept of genetics and cell biology often called recombination. It occurs during meiosis .

Crossing over during meiosis with chiasma shown. In genetics a chiasma (pl. chiasmata) is the point of contact the physical link between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma an exchange of genetic material can occur between both chromatids what is called a chromosomal crossover but this is much more frequent during meiosis than mitosis.
