Question

What would happen if they crossed a yellow jellyfish with a goober? Complete the Punnet square to help you determine the probability for each color of jellyfish. (Incomplete dominance)a) Give the possible genotypes for the offspring.b) What percentage of the offspring would be yellow?c) What percentage of the offspring would be blue?d) What percentage of the offspring would be "goobers" (yellow-blue)?

Answer 1

Starting with the Punnet square, the yellow would have the genotype YY and the goober would have the genotype YB, so the cross YY x YB would be as follows:

a) As we can see, the offspring would be 50% YB and 50% YY.

b) 50% (half) of the offspring would be yellow (YY)

c) 0% (none) of the offspring would be blue (BB)

d) 50% (half) of the offspring would be goobers (YB)
