Answer:
d
Explanation:
<em>Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.</em>
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.
Correct option: d
Homozygous means that it has the same alleles and lower case represents a recessive trait therefore the genotype for a homozygous recessive individual is: bb
