A researcher crosses mice with brown eyes and short tails, and the F1 progeny were recovered in the following numbers and phenotypic classes: F1: 32 apricot, short : 30 brown, long : 139 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) Give the expected number of individuals in the "brown, short" class. b) What is your null hypothesis for the chi-square test?. c) You obtain a value of 8.59 for the chi-square test. What conclusion can you make froh the results of the chi-square test? d) Making use of the appropriate genetic convention for naming alleles, give the genotype of any of the progeny in the "apricot, short" class.

Transcribed Image Text:A researcher crosses mice with brown eyes and short tails, and the F1 progeny were recovered in the following numbers and phenotypic classes:
F1: 32 apricot, short : 30 brown, long : 139 brown, short : 9 apricot, long
