Question

A wild-type chromosome can be represented as ABC[*]DEFGH, and from this a chromosomal aberration arises that can be represented ABC[*]DEgfH, where [*] represents the centromere. If there is a crossover between a mutant chromosome and a normal chromosome between G and F, what are the resulting recombinant chromosomes?

Answer 1

Answer:

The resulting recombinant chromosomes will have the following chromosomes:  

A. ABC[*]DEGGH

B. ABC[*]DEFFH

Explanation:

In consequence, the resulting recombinant chromosomes will have one duplication for either the G gene or the F gene, and one deletion for the other. Duplications are genomic rearrangements produced by unequal recombination events
