The intestinal villi crypts will make a wave area on the intestine wall so it will broaden the surface area of intestine. When the surface area of intestine become broader, intestine will absorb more food.
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.
