Because his last undergrad research assistant died on the job, Professor Farnsworth has assigned
you the unfortunate task of assessing relatedness among giant killer space wasps. Like Earth
wasps, the space wasps have a system of inheritance known as “haplodiploidy” in which haploid
males are produced from unfertilized eggs and diploid females are produced from fertilized eggs.
Each female makes a single mating flight, during which she collects—from one or multiple
males—sperm that she uses to fertilize eggs throughout her life. Male space wasps also make a
single mating flight during which they may fertilize one or more females. Fill in the following
table with the probability that two individual space wasps share zero, one, or two alleles of the
nuclear genome identically by descent. In the rightmost column, labelled r, give the relatedness
coefficient of the two individuals. Show your work or explain your reasoning under the table or
