Answer:
A.) Core
Explanation:
Core definition: a central and often foundational part usually distinct from the enveloping part by a difference in nature.
Allele for gray fur is A (dominant)
Allele for white fur is a (recessive)
Genotype of heterozygous is Aa (heterozygous is gray, because its allele is dominant)
If we cross two heterozygous
<span>Parents: Aa x Aa
</span> <span>F1: AA Aa Aa aa</span>
The ratio between phenotypes is 3:1 (gray:white)
<span>AA Aa Aa are with gray fur</span>
<span>aa is with white fur </span>
<span>Because the bases can be arranged in many different combinations</span>
