Question 11 1 pts You are a scientist trying to understand how wing shape is inherited in fruit flies. You have flies that are pure-breeding for the wild-type wing shape &flies pure-breeding for a mutant wing shape (zigzag wings). You breed these flies and notice that the F1 are 100% wing mutants. Using your F1 data you've constructed a null & alternative hypothesis. Now you want to attempt to falsify the null hypothesis so you cross a male & female from your F1 generation flies. Assuming basic Mendelian inheritance, which of the following are the expected wing phenotype ratios for the F2? O 50% wild-type, 50% wing mutant 0 100% wild-type O 25% wild-type, 75% wing mutant 0 100% wing mutant O 75% wild-type, 25% wing mutant

Explanation / Answer

11. X-Linked dominant
    Female XAXA X XaY Male

F1          XAXa   XAY

F2   XAXA XAY XAXa XaY

75% wildtype and 25% mutant
