Question

Consider a situation where you have a parental cross with the mother and father phenotypes listed below. Remember that the genotype for the wild-type parent is always homozygous.

 

The counts of the F1 offspring are listed in Table 1. Two randomly selected individuals are selected and mated to produce a set of F2 individuals. If you test the F2 counts to determine whether they are consistent with an autosomal recessive mode of inheritance, what is your decision? Use a 0.05 significance level.

 

PARENTAL CROSS

 

Parental cross: Mother with wild type phenotype, Father with disease phenotype.
