Answer:

Pleiotropy

Explanation:

Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism

  • <em>gene pleiotropy</em>
  • <em>developmental pleiotropy</em>
  • <em>selectional pleiotropy</em>
  • <em>antagonistic pleiotropy </em>

<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>

Nana76 [90]

NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.

<h3>What is nicotinamnde adenine dinucleotide?</h3>

The nicotinamnde adenine dinucleotide (NAD) is a coenzyme used in the transport electron chain of the cellular respiration.

The movement of electrons is coupled to a proton gradient in order to generate ATP, the energy coin of the cell.

In conclusion,  NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.

By using a genetic diagram or a punnett square, we can show the the result of a cross between RR and rr.
The result of the genotypes should all be Rr.
This means all their offsprings should have the dominant trait being expressed.
Therefore, the percentage to this should be 100%.
The picture above is an example of using a punnett square finding the possible genotypes of the offsprings.
