Question 5: Consider the following genetic map from Mischievous gremlinus: A 6.0 CM B C 13.4 CM + Interference among these genes is 0.5. A parental cross is performed between AABBCC and aabbcc. The F1 generation is then testcrossed. The F2 progeny included 1,000 offspring. What are the different classes produced, and in what numbers? Assume that reciprocal classes of recombinants are obtained in equal numbers. 4 E DAWWW Create and Share Request Adobe PDF Signature Adobe Acrobat 1

I II III II-1 11-2 Aa 1-1 11-3 Aa 1-2 II-4 III-1 Example: Given the pedigree above, what is the probability that the granddaughter (III-1) will be heterozygous? In order to determine the probability that III-1 is heterozygous, we need to determine the probability of the possible genotypes for her mother (II-2). Because the grandparents are both heterozygous, we would expect the following genotypic ratios in their offspring: ¼ AA, ½ Aa, and 14 aa. However, we have to use all possible information, and the circle representing III-1 is not shaded in, so she cannot be aa. Therefore, we eliminate the probability that II-2 is aa, and the final probability for II-2 is 1/3 AA and 2/3 Aa. We assume II-1 is AA because he is marrying into the family and we assume everyone marrying into a family is homozygous wild-type, unless proven otherwise. If II-2 is AA, and we assume II-1 is AA, then there is no chance that their daughter (III-1) is Aa If II-2 is Aa, and we assume II-1 is AA, then there is a…
