No, it would not be possible since both alleles in the genotype are recessive. If the alleles were xx for square jaws, then
x x
x xx xx
x xx xx
would be the possible genotypes for the offspring
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.
