The variation in weight in a population may be explained by the segregation of 10 genes that control weight in a simple ____________genetic fashion, the distribution will be ____________ from the lowest value (____________ for one allele at all 10 genes to the highest value (____________ for the other allele at all 10 genes).

Respuesta :

Answer:

Additive; continuous; homozygous; homozygous.

Explanation:

The variation in weight in a population may be explained by the segregation of 10 genes that control weight in a simple additive genetic fashion, the distribution will be continuous from the lowest value homozygous for one allele at all 10 genes to the highest value homozygous for the other allele at all 10 genes.

Continuous phenotypic variation can be caused by many genes affecting a trait and/or environmental variation.
