STUDY / REVIEW PRACTICE MENDELIAN GENETICS QUESTIONS FROM PREVIOUS BIOLOGY 25 EXAMS 1. A New York Times article entitled “Mice Ignore Mendel’s Laws” (5/26/06), pointed out that “anomalous findings are often dismissed in science, because researchers believe the experiment must have come out wrong or that it is not worth the effort of tracking down the cause.” Describe one possible experiment that Mendel himself might have done with his garden peas where he might have dismissed the results because he could not reconcile them with his theory of ‘discrete factors’ (alleles of genes) that obeyed the law of ‘equal segregation. (In your answer be sure to explain why Mendel might have considered the results in the experiment you describe anomalous.) 2. Although a single diploid individual can carry only two different alleles for a given gene, more than two alleles may still occur in a population. One example is the A, B, and O alleles for antigen proteins on the surfaces of human red blood cells. Another example is a gene that controls coat color in rabbits. Four alleles are found: C (gray), C ch (“chinchilla”, silver-gray), C h (“Himalayan,” white with dark tips of the extremities), and c (albino white). The order of dominance of these alleles is: C > C ch > C h > c . a) If a gray rabbit of genotype
