Consider a hypothetical quantitative trait (a weight of some kind) affected by f

Question

Consider a hypothetical quantitative trait (a weight of some kind) affected by five loci. Assume the following:

NO DOMINANCE at any loci
The independent effect of each dominant gene is +10 lbs.
The independent effect of each recessive gene is -4 lbs.
For homozygous combinations, genotypic values are equal to breeding values.
? = 600 lb.


For the genotype AaBbCcDdEe, find the breeding value (BV) and genotypic value (G).

I attempted to solve this problem but I'm not entirely sure if I went about it in the correct manner. In regards to the breeding value (BV) I came up with 5(+10) + 5(-4) = +30 [I basically added the values of each allele]
As for the genotypic value (G) I got 5(10-4) = +30. [Being that they're heterozygous, I'm guessing that the dominant/recessive gene will effect each other].

If I'm way off with my answers, could you please tell me what I'm doing wrong. I have a hard time distinguishing the difference between a genotypic value and breeding value. Any help with this will be greatly appreciated.

Thank You!!
Ana
