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 there is equal segregation of alleles at the py locus.
- What is the correct chi-square value and how many degree(s) of freedom should be used in its interpretation?
