Question

The data set below summarizes progeny (F2 generation) resulting from a cross between two F1 individuals, originating from a cross of two true breeding Drosophila strains (P generation), which differ with respect to two traits. Produce a hypothesis about the mode of inheritance of the genes and analyze whether the data fits your hypothesis by using the Chi-square test.

29 wild type, males

24 wild type, females

9 vestigial wings, females

10 vestigial wings, females

11 ebony body, males

8 ebony body, males

4 vestigial wings, ebony body, males

5 vestigial wings, ebony body, females

Explanation / Answer

The problem tells you that 2 true breeding strains are interbred, meaning one parent is homozygous for both dominant alleles and the other parent is homozygous for the recessive alleles. This would produce the f1 which would be all heterozygous offspring. Data is required for framing hypothesis and testing it .

A chi square statistics is used to investigate whether two distribution of categorical variables differ from each other.chi square test can be used on actual number and not on percentage , proportions etc
