In Flower Beetles, Pygmy (Py)is Recessive to Normal Size (Py⁺)

Multiple Choice

In flower beetles, pygmy (py) is recessive to normal size (py⁺) , and red color (r) is recessive to brown (r⁺) .A beetle heterozygous for these characteristics was test crossed to a beetle homozygous for pygmy and red.The following are progeny phenotypes from this testcross: Carry out a series of chi-square tests to determine if the two loci are assorting independently.What is the CORRECT chi-square value and how many degree(s) of freedom should be used in its interpretation?

A) 112 with one degree of freedom
B) 265 with three degrees of freedom
C) 367 with four degree of freedom
D) 16.5 with three degrees of freedom
E) 367 with three degrees of freedom
