Another genetics question: multiple genes at different loci?
E.W. Lindstrom crossed two corn plants with green seedlings and obtained the following progeny: 3583 green seedlings, 853 virescent-white seedlings, and 260 yellow seedlings. Give the genotypes for the green,virescent-white, and yellow progeny.

My hypothesis is that the progeny has the ratio of 12 : 3 : 1, meaning that two pair of genes involve in the phenotype.
Phenotype .....| genotypes
Green ............| A-B- and A-bb
virescent-white | aaB-
yellow ............| aabb
I suggest the interaction between the two genes is dominant epistasis, where dominant allele A suppresses the expression of allele B and b from different locus.
You may check the hypothesis using Chi-Square test.

Black Coat Dominant = B Brown Coat Recessive = b complicated Coat Dominant = R gentle Coat Recessive = r 6 BbRr or BBRR 2 bbRr or bbRR 6 Bbrr or BBrr 2 bbrr (in simple phrases because of the reality they're thoroughly recessive) the daddy and mom could desire to have the recessive trait. optimal in all danger hybrids. could help greater beneficial yet out of time in library sorry.
