The eye color of mice is determined by a dominant allele E, corresponding to black eyes, and a recessive allele e, corresponding
to red eyes. If two mice, one of genotype EE and the other of genotype ee, have offspring, compute the probability of one of the offspring having red eyes. Hint: Draw a Punnett square. (Enter the probability as a fraction.)
There's only one possible genotype the offspring can have: Ee. Since E is dominant, the offspring will have black eyes. So the probability of one of the offspring having red eyes is 0.
