5. Consider the following genotypic values for marbling score (scale = 1-9) in cattle for a simple genetic model with one locus and two alleles. A2A2: 4.0 A1A2: 5.2 A1A1: 6.0 Consider a population with an allele frequency of A1 of 0.25. Assume Hardy-Weinberg equilibrium for the genotype frequencies. a) Calculate the population mean (hint, sum over the 3 genotypes the genotypic frequency x the genotypic value) b) What is the expected progeny mean for an A1A1 bull? c) What is the breeding value of an A1A1 bull? d) GENE351 students only. If the frequency of the A1 allele was 0.8 what is the breeding value of an A1A1 bull?
