The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups.
<h3>How do phenotypic classifications work?</h3>
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups. If any of the single homozygous recessive genotypes (i.e., A bb or aaB_) exhibits the same phenotype as the double homozygous recessive (aabb), then a 9:3:4 phenotypic ratio will result.
<h3>What does phenotypic classification entail?</h3>
phenotype, all of an organism's observable traits that emerge from the interaction of its genotype (total genetic inheritance) and environment. Observable features include things like behavior, biological characteristics, colour, shape, and size.

EDTA inhibits the activity of DNase during DNA isolation process.
DNase is an enzyme which degrades DNA using divalent metal ions like Mg^{2+} . These metal ions act as cofactor for the proper functioning of DNase.
EDTA chelates the divalent metal ions and thus does not allow DNase to access them.
Therefore in this way DNA is prevented from degradation during its isolation.
Answer:B. Primary consumer
Explanation:The reason why Its b because that primary comsumers are mostly herbivores or the primary comsumer is the first consumer to eat the producer.Hope it helps!
