Frogs have the trait of being the tetrapod.
Explanation:
when the female frogs lays her eggs directly in the water and fertilized eggs are hatched into aquatic tadpoles, on maturity they acquire legs and lungs. tadpoles have tails which is lost during the metamorphosis and the frogs also acquire the carnivorous tastes.
As evident that the male clasps the female from her back and releases the sperm through which the fertilized eggs are laid into water by the female frogs, mature frogs develops the trait of tetrapod. A Tetrapod animal is the one having four pods or four legs. A complete metamorphosis occurs in the life cycle of the frog.
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.
