Please answer question 7,8 and 9 BXFontCase 2: Delta 32 and the Black PlagueDr. O'Brien extended his findings about the delta 32 mutation by looking for the mutationin descendants of survivors of the black plague in Great Britain. Because the bacteriumthat causes plague also begins its attack on the body by entering white blood cells,O'Brien wondered if this deadly disease could have selected for individuals with themutation. He tested people in a small town in England in which about half thepopulation had never become ill when the plague struck the community in 1665. Hefound a much higher percentage of the townspeople had the delta 32 mutation than inthe populations of other continents. If O'Brien is correct, this mutation providedprotection from an epidemic that killed 1/3 of Europeans. The heterozygous conditionwould probably have delayed onset of symptoms.William was a survivor of the plague in 1665 because he was homozygous for the delta 32mutation (D'D'). He moved to a town in England that was unaffected by the plague andmarries Elizabeth who was homozygous normal (DD).F7. Based upon what is now known of William and Elizabeths' genotypes, what is theprobability they could have a child with the partial resistance phenotype? Solvea Punnett Square to estimate this probability. Show your work below.MULTIPLE ALLELES and CODOMINANCESometimes there are multiple possibilities for a particular gene. When there are morethan 2 possible alleles, the dominance relationships of all the alleles must be determined.An example of a trait governed by multiple alleles is ABO blood type. There are 3 allelesfor the gene that codes foda protein located on the surface of red blood cells: I, I, andįrand fare co-dominant. codes for the A protein, while I codes for the B protein.When both and are present, both proteins are made. Therefore, and I are co-dominant. Both and I are dominant over i which does not code for any membraneprotein.
