Assuming independent assortment, an individual of genotype ssyyaa would produce gametes of genotypes (in their correct proportions) see section 14.3 (page 297) .

1/8 SYA, 1/8 SYa, 1/8 SyA, 1/8 Sya, 1/8 sYA, 1/8 sYa, 1/8 syA, 1/8 sya

Explanation:

The given genotype is heterozygous for three genes. Considering that all the genes assort independent of each other, the given genotype will form a total of 2^3= 8 types of gametes in equal proportion. During gamete formation, two alleles of a gene (S and s, Y and y, A and a) would separate from each other randomly. This would form a total 8 different types of gametes with the following genotype:

1/8 SYA: 1/8 SYa: 1/8 SyA: 1/8 Sya: 1/8 sYA: 1/8 sYa: 1/8 syA: 1/8 sya

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

c is the correct answer hope this !
