2. 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?
There is a comment regarding needing more knowledge, but I'm not sure what else you would need to answer this question other than a background in genetics.

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...

Which of the following is TRUE of incomplete penetrance? Select one: a. Epistatic interactions can result in incomplete penetrance in some cases. b. Environmental factors do not influence penetrance. c. Incomplete penetrance implies that some individuals will experience less severe forms of disease, such as cancer or Alzheimer's. d. Incomplete penetrance is never observed with Huntington's disease e. Incomplete penetrance refers to cases in which individuals developing a particular disease (e.g., cancer or Alzheimer's) lack the typical genotype for this...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
