What is the recombinant frequency between a and b? between, Ask an Expert

Academics

You have a drosophila line that is homozygous for autosomal recessive alleles a,b, and c, linked in that order. You cross females of this line with males homozygous for the corresponding wild-type alleles. You then cross the F1 heterozygous males withe their heterozygous sisters. You obtain the following F2 phenotypes (where letters denote recessive phenotypes and pluses denote wild-type phenotypes): 1364 +++, 365 abc, 87 ab+, 84 ++c, 47 a++, 44+bc, 5 a+c, and 4 +b+.

A. What is the recombinant frequency between a and b? Between b and c? (Remember there is no crossing over in drosophila males)

B. what is the coefficient of confidence?
