Explanation / Answer

A punnett square allows one to easily calculate the probability of genotypes and phenotypes among offspring.

The product rule of probability tells that to determine the chances of independent events , such as the likelihood of inheriting a certain allele , probabilities are multiplied.

The chance of inheriting either an E or an e from a heterozygous parent is 50% . Therefore the chance of the offspring having the genotype Ee is 25% and eE is 25%. The sum rule tells us the probability of producing a heterozygous offspring is therefore 50%.

The sum rule of probability states that when the same event can occur in more than one way , the results are added.

In the figure to the left , the chance of EE is 25% , The chance of Ee is 50% , and the chance of Ee us 50% , so the probability of an offspring with a dominant phenotype is 75%.
