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.
These are similar because they both included desired characteristics. They are different because artificial selection has to do with humans being involved. where natural selection is with out humans being involved and is life or death.
