Question

The color of some beans is controlled by three different genes, A, B, and C, making bean color a polygenic treat if we start with parents that are heterozygous for each gene, then for each indvidual genotype, probability can be deduced using a simple Punetf square Below Cc aAa AA 25% cc-25% probability (And Rule or Or Rule) would be used to determine the probability of a bean with the genotype AABBCC? product rule The probability of a bean being AABBCC is 0 0156 Report your answer as a percent and round to two decimal places

Answer 1

1). And rule has to be used. And rule is used to find the combined probability of multiple events happening simultaneously when outcome of individual events does not affect the outcomes of others that is they are mutually exclusive. In and rule the end probability is the product of individual probabilities.

Or rule is used when the outcome of an event impacts that of other events. Here the selection of genes of a trait is independent of that of others.

Answer. Therefor to calculate the probability of a bean being AABBCC is the individual probabilities would need to be multiplied

2. The probability of a bean being AABBCC = probability of AA × probability of BB × probability of CC = 0.25×0.25×0.25 = 0.15625

Probability is 15.62%
