Table 2 below shows the banding pattern for a cross between parents P1 and P2 producing the 6 progeny I1-6. The parents are double heterozygotes for two independently assorting genes.
Identify the pairs of bands that correspond to the two segregating pairs of alleles.
Assuming independent assortment, what is the probability that an offspring shows the pattern observed in I5.

Individual #9 marries an unaffected individual (not shown). They have four children, two boys, and two girls. How would I use Punnett squares to show the possible gametes that would result from these two parents? Is there a difference in the probability of sons vs. daughters displaying the trait?
For individual lll-6, how do you get 2/3 for the probability of heterozygous? What are the three offspring you're talking about?
