lecture 10- genetic variation Flashcards
1
Q
two genes: complementary gene action
A
products of 2 gene loci complement each other to produce a phenotype. one dominant allele at each locus is required for full expression of the phenotype (9:7 ratio)
2
Q
dominant epistasis
A
the dominant phenotype at one gene affects the expression of alleles of another gene (12:3:1 ratio)
3
Q
recessive epistasis
A
9:3:4 ratio
4
Q
supression
A
one gene masks the expression of a specific allele of another gene (13:3 ratio)
5
Q
duplicate genes
A
15:1 ratio
