Question

Assuming basic Mendelian inheritance, you propose a alternative hypothesis based on your F1 fruit flies:

Question 10 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. Assuming basic Mendelian inheritance, you propose a alternative hypothesis based on your F1 fruit flies; I hypothesize that the zigzag wing phenotype is recessive to the wild-type wing phenotype I hypothesize that zigzag wing phenotype is both dominant and recessive to the wild-type wing phenotype I hypothesize that the zigzag wing phenotype is dominant to the wild-type wing phenotype I hypothesize that the zigzag wing phenotype is neither dominant nor recessive to the wild-type wing phenotype

Explanation / Answer

Ans: I hypothisize that zigzag wing phenotype is neither dominant nor recessive to the wild-type wing phenotype.

This is a monohybrid cross in which only one trait is involved in a cross. According to Mendelian inheritance, the ratio for a monohybrid cross is 3:1, with 3 portion show dominant character over 1 recessive.

Here, all the F1 offsprings are zigzag shaped wing mutants. Thus 3:1 ratio does not fit for F1 in the cross. Thus it does not suggests that one wing shape is dominant or recessive to the other wing shape.
