A researcher crosses mice with brown eyes and long tails, and the F1 progeny were recovered in the following numbers and
F1: 6 apricot, short : 30 brown, long : 15 brown, short : 9 apricot, long
You know the genes encoding these traits are autosomal, completely dominant and assort independently. You want to use a chi-square test to analyse these results.
a) Making use of the appropriate genetic convention for naming alleles, give the genotype of the male parent in this cross.
b) What is your null hypothesis for the chi-square test?
c) Give the expected number of individuals in the “brown, long” class.
d) You obtain a value of 3.47 for the chi-square test. What conclusion can you make from the results of the chi-square test?
