Question

What phenotypes could result from the mitotic crossing over in an individual that is heterozygous for the recessive loci of singed bristles (sn), yellow cuticle (y), and bent bristles (b) given the loci are arranged as follows:

Answer 1

Answer: Hello your question has some missing data attached below is the missing data

answer : single spots for “b”, “sn”, and “y”  ( option C )

Explanation:

During the mitotic crossing over in a heterozygous individual the phenotypes that could result are single spots for “b”, “sn”, and “y” . this is because  In mitosis/mitotic crossing there is no pairing up and no swapping of chromosomal segments Hence no variations are introduced during mitosis /mitotic crossing
