Question

4. You cross individuals with the following Genotypes, AaBbDdEeFFGg & AaBbDDEeFfGg. Predict the proportion of offspring that would show the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AabbDdEeFfgg, C) the Genotype: AABbDdEeFfgg, D) the Genotype: aaBbddEeffGg, & E) all Recessive Phenotypes.

5. You cross individuals with the following Genotypes, AaBbDdEeFFgg x AabbDDEeFfGg. If you produce 1000 offspring in this cross, predict the number of offspring that would have the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AABbddeeFfGg, C) the Genotype: AABbDdEEFfGG.

6. You are examining 2 genes: A & B. In the A gene, Red eyes are Dominant to Blue eyes. In the B gene, Wings is Dominant to Wingless. You cross T.B. lines to produce a Heterozygous F1 i.e., the F1 is AaBb. You cross a male & female from the F1 to produce an F2 generation. You randomly select an individual from the F2 that exhibits both Dominant traits & cross them to a test i.e., the selected individual has the Genotype A_B_. Among the progeny you produce, you see ½ have Red eyes & Wings. The other half of the offspring have Blue eyes & Wings. Based on this information, what was the Genotype of the F2 individual?

7. You are examining 2 mutations. The 1^st is an Autosomal Recessive & the 2^nd is an Autosomal Dominant. In your P generation, the male is T.B. & has both mutations. The female in the P generation is T.B. & Wildtype. Predict the Phenotypic ratio you would observe in the F1 & F2 generations?
