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.

Enzyme may work if in it's optimum pH if the pH didn't match with the enzyme's pH, the enzyme will break down.
Enzyme will break down if the temperature so high it's called denaturation.
it is B cells produce antibodies and T cells destroy infected cells
