Final answer:
The phenotypic ratios in the progenies of heterozygotes for 5 loci can be calculated using the product rule. The overall phenotypic ratio would be 1:1:1:1:1.
Step-by-step explanation:
The phenotypic ratios in the progenies of heterozygotes for 5 loci can be calculated using the product rule.
The probability of each genotype at each locus can be determined by using the sum rule.
Let's assume that the heterozygotes have a probability of 1/2 for each locus, while the homozygotes have a probability of 1/4.
Using the product rule, we can calculate the overall phenotypic ratio by multiplying the probabilities of each genotype for each locus.
For example, if we have 5 loci, the overall phenotypic ratio would be (1/2)⁵ : (1/2)⁵ : (1/2)⁵ : (1/2)⁵ : (1/2)⁵. Simplifying this expression gives us a phenotypic ratio of 1/32 : 1/32 : 1/32 : 1/32 : 1/32, or 1:1:1:1:1.
