answer parts a, b, and c please ### Snail Shell Color and Genetic PathwayIn snails, the two allelic pairs A, a and B, b are important for pigment deposition in the adult's shell. The diagram illustrates the pathway where the dominant alleles A and B are both necessary for a colored shell. The absence of either results in white shells.**Diagram Explanation:**- **A Snails**: Convert Compound A to Compound B using Enzyme I. The absence of the "A" allele (as in "aa" snails) results in a white shell because Compound A cannot be converted.- **B Snails**: Convert Compound B to Compound C using Enzyme II. The absence of the "B" allele (as in "bb" snails) results in a white shell because Compound B cannot be converted to Compound C. - **Colored Shell**: Requires both dominant alleles A and B to produce Compound C from Compounds A and B.### Questions and Answers:**a) What is the genotype and phenotype (Colored or white) of a dihybrid snail for these two loci?** - Genotype: AaBb - Phenotype: Colored**b) A colleague hands you a white snail and assures you that it is heterozygous at the “A” locus. What is the genotype of the snail?** - Genotype: Aabb**c) What kind of shells, colored or white, are to be expected from a cross of two double heterozygotes (dihybrids) for genes A and B and in what ratio?** - Ratio: 9 Colored:7 White**d) What type of epistasis is being demonstrated in this question?** - Epistasis Type: Recessive epistasis**e) Assume that another allelic pair in snails also determines shell color. The presence of the dominant allele, R, produces red shells. Its recessive allele, r, produces yellow shells. What would be the phenotypes of the following snails in relation to shell color?** - i. AaBbRr: Colored, Red - ii. AaBbrr: Colored, Yellow - iii. aaBBRR: White
