1) a. In a population of 100 inbred genotypicallyidentical rice plants, variance for grain yield is 4.67grains2. What is the heritability for yield?

b. Would you advise a rice breeder toimprove yield in this strain of rice plants by selection?

2) In a cross between a strain of large guinea pigs (1200g)and a strain of small guinea pigs (700g), the F1 are phenotypicallyuniform with an average size of about 950g. The F1 guinea pigs areallowed to interbreed to produce F2. Among 1014 F2 individuals, 3are about the same size as the small parental strain and 5 areabout the same size as the large parental strain.

a. How many loci are involved in the inheritance of size inthese strains of guinea pigs?

b. Make a rough estimate for the Vp for body sizein the F2 population.

c. Can you estimate VG for the F2 population?
