Explanation:
<u>D. 6</u>
There are two forms of the gene, CTGT and TGTC, called alleles. These have undergone 3 crossover events, which may create two separate copies.
Thus 2 × 3 (# of events)= 6 new alleles
The interchange of chromosome segments, including homologous non-sister or identical chromatids. Crossing over happens at chiasmata, where non-sister chromosomes are fused together.
Further Explanation:
DNA variants on chromosomes,may have different forms called alleles. DNA, which is a genotype, is transcribed into mRNA and then converted into amino acids that are linked together by rRNA to form proteins that make up the morphology of the individual.

A heterogeneous mixture composes of non- uniform components, so the concrete would be the answer, because you can tell the components from one another.
The well - designed experiment test one factor at a time. The answer to the question above is letter A. 1. The items that are being tested are the independent variables and that they cause the dependent variables to change.
