The correct answer is silent mutation .
There are sequences present in the body where a point mutation occurs but the protein formed is still the same
Assuming Complete Dominance, Only 1 copy of a Dominant allele of a specific trait is needed to exhibit that trait.
This control is called negative feedback. Mechanism of negative feedback. Each metabolic reaction or process is regulated by several enzymes. These enzymes control the rate of these reactions and thus are fundamental in maintaining homeostasis. In a negative-feedback pathways, the end product of a pathway binds to the allosteric site of the first enzyme, closing its active site and blocking the rest of the reactions.
