What is the importance of crossing-over?

nikklg [1K]

Answer:

b.It increases the likelihood that daughter cells contain different genetic material.

Explanation:

Morgan and Cattell for the first time used the term ‘crossing over’. Crossing over takes place during prophase I of meiosis. During crossing over, chromosome segments of non-sister chromatids of homologous chromosomes get exchanged. As a result, the daughter cells acquire different genetic materials. Thus, it provides genetic variation by creating a new combination of genes or get recombination and produces hybrids.
