A researcher crosses mice with apricot eyes and long tails, and the F1 progeny were recovered in the following numbers and phenotypic classes: F1: 21 apricot, short : 30
A researcher crosses mice with apricot eyes and long tails, and the F1 progeny were recovered in the following numbers and
F1: 21 apricot, short : 30 brown, long : 19 brown, short : 110 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) What is your null hypothesis for the chi-square test?
b) You obtain a value of 11.33 for the chi-square test. What conclusion can you make from the results of the chi-square test?
c) Give the expected number of individuals in the “apricot, long” class.
d) Making use of the appropriate genetic convention for naming alleles, give the genotype of any of the progeny in the “apricot, long” class.
