Question

You propose a null hypothesis based on your F1 fruit flies;

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 null hypothesis based on your F1 fruit flies; I hypothesize that the zigzag wing phenotype is neither dominant nor 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 recessive to the wild-type wing phenotype I hypothesize that the zigzag wing phenotype is dominant to the wild-type wing phenotype.

Explanation / Answer

c)I hypothesize that the zigzag wing phenotype is recessive to the wild type wing phenotype because the wild type wing is dominant as F1 has 100% wing mutants which means the zigzag wing are 0%.
