Explanation:
they have multiple layers of minerals
Answer:
a. (A_B_),(A_bb)(aaB_)(aabb)
Explanation:
This scenario is an example of recessive epistasis.
It involves two recessive alleles concealing the expression of an allele at varying locus.
The 9:7 ratio seen in this case is a rare form of epistasis known as duplicative recessive epistasis (a situation in which the other gene expression are masked due to the effect of either aa or bb presence on them).
In this scenario, if snails possess two copies of one or the other allele I.e allele a or allele b, pigment production would be inhibited leading to albino individuals.
A recessive phenotype is seen for a homozygous recessive gene at Gene A or Gene B.
Therefore, the genotypes of the offspring is AABB, AaBB, AABb, aaBb, aaBB, AAbb, Aabb and aabb.
