Not sure why that's an interesting one maybe it's a good thing to look it up on Google or something

carbo hydrates and lipid if not lipids then proteins.
Answer:
B) The completely-plated phenotype is controlled by a dominant allele of a single gene.
Explanation:
<em>The results from the breeding experiment showed that the completely-plated phenotype is controlled by a dominant allele of a single gene because it followed Mendelian pattern of inheritance.</em>
According to Mendel, in a dominant/recessive gene situation, the recessive gene do not manifest physically in F1 generation and at F2, the phenotypic ratio of dominant to recessive gene is usually 3:1.
For example, assuming the completely-plated gene is represented by P and the alternate form (low-plated) by p.
At F1: PP x pp
Progeny: all Pp, completely-plated stickleback in appearance.
At F2: Pp x Pp
Progeny: PP, Pp, Pp, and pp
3/4 of the progeny have completely-plated appearance while 1/4 have low-plated appearance. The ratio of completely-plated to low-plated is 3:1.
The correct option is B.
C Its the only one that actually affects the bird population.
Spilling breaker. The second one :)
