To use alternative Models of gene action

The goal of this exercise is to use alternative models of gene action. Consider a hypothetical locus that influences the weight of chicken. The locus has alleles H (heavy) and L (light). When fed the same diet,HH chicken weigh 3.5 kg, and LL chicken weight 2 kg. Answer the following questions and show your work supporting your answers:

 

1a) [10 points] For the HL chicken indicate the expected weight if the locus exhibits no dominance.

 

 

1b) [25 points] For the HL chicken indicate the range of weights if the locus exhibits partial dominance and H is the dominant allele.
