A diploid yeast was ABD on one chromosome and abd on the other. The yeast cell underwent meiosis and the four genomes in the resulting tetrad were analyzed and determined to be: ABD, ABD, aBD and abd.
(a) For the moment, focus on the outcome regarding the number of B versus b genes. (Ignore D and d.) What is unexpected, regarding the number of gene types in the meiotic cells? Rationalize how this could have happened, assuming that this outcome had something to do with recombination.
(b) Is there a second "unexpected" outcome, and, if so, what is it? Assume that this second outcome occurred in a process that was linked to the first outcome, which happened with the B/b gene. Explain how they both might have occurred together.
(c) What is the name associated with the outcome: ABD/ABD/aBD/abd?

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
