Answer: True

Explanation:

The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to produce water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles.(TCA) FADH2 is only produced in Krebs cycle.

Suppose a gene has two alleles, one of which is dominant over the other. An individual whose genotype is for the recessive allel
Trava [24]

Answer:

This question is incomplete, the options are:

A. Two copies of the allele that determines phenotype whenever the allele is present

B. Two copies of the allele whose effect is hidden unless the other allele is absent

C. One copy of the allele that determines phenotype when present and one copy of the other allele

D. One copy of each of two alleles that both contribute equally to determining phenotype

The answer is B.

Explanation:

According to Gregor Mendel, a Gene comes in two alternative forms called ALLELES. One allele called the DOMINANT ALLELE is capable of masking the phenotypic expression of the other called the RECESSIVE ALLELE. The dominant allele will always express itself whenever it is present. However, a recessive trait will only be expressed when two alleles for recessiveness occur in the gene.

An individual whose genotype is for the recessive allele will have two copies of the allele whose effect is hidden unless the other allele is absent. This means that in that particular gene, the two present alleles will be recessive alleles.
