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.
Answer:
The scientist would be an ecologist i.e. an expert in ecology.
Explanation:
The scenario in question investigates the affect of a biotic factor (beaver population) on various abiotic factors such as water flow and soil nutrient content.
In this context, ecology is the scientific study of interactions between biotic and abiotic components of an ecosystem.
The answer is "a" if the second word is "bends" not "burns".
