Title: Consider the following hypothetical case: Post by: amer157 on Nov 28, 2011 In some birds, a dominant gene is lethal. When a homozygous dominant gene is lethal, a heterozygous condition results in short and crooked wings, and a bird that is homozygous recessive is normal in wing structure.
What is the phenotype ratio if two heterozygous short and crooked-wing birds were crossed? A. 3 : 1 B. 1 : 1 C. 2 : 1 D. 1 : 2 : 1 Title: Re: Consider the following hypothetical case: Post by: itseasy on Nov 28, 2011 Content hidden
