Answer:
8 black guinea pigs
Explanation:
We're given that the black fur color is the dominant trait, meaning that this problem deals with complete dominance. In complete dominance, having just one allele is enough to express a certain phenotype. So let's say the female guinea pig has the genotype BB for homozygous black. The male would be bb since he's homozygous white, and the color white is recessive. Cross this and you get the genotypes Bb. But remember that even having one dominant allele will be sufficient to express the dominant phenotype. So all guinea pigs shall be black in fur color.

The options are
a. A lack of estradiol.
b. Moderate levels of estradiol during an early stage of development.
c. A high level of testosterone during an early stage of development.
d. A high level of testosterone during the late part of puberty.
The answer is b. Moderate levels of estradiol during an early stage of development.
Testosterone is a hormone which is responsible for the secondary sexual characteristics of a male while estradiol is the hormone responsible for the secondary sexual characteristics of a female.
This is why estradiol is the hormone responsible in female development regardless of the chromosomes

<span>A </span>biological system<span> or also called, a biotic community is composed mainly of living organisms. These organisms can be classified into the main layman categories of animals and plants, majorly. These creatures can be more furthered classified by how they eat and survive. Plants can make their own food through, photosynthesis. Animals eat and are dependent. Can be classified into subtypes as: herbivores, omnivores and carnivores. What makes all of these organisms a biotic community or a biological system is they contain cells, cells are the basic unit and foundation of every living thing.<span>
