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.

Identify: Carbon Dating
Answer:
Pea plant flowers of two colors were used i.e., Purple and White. He observed the same ratio in both cases (3:1), in the self and cross pollination. This happens because of the assumptions in Law of Segregation and Law of Independent assortment. He concluded that the purple color is the Dominant and white in recessive as in both self and cross pollination procedures.
