Q596
The dihybrid ratio 9 : 3 : 4 indicates which gene interaction
A.
Complementary gene action
B.
Inhibitory genes
C.
Supplementary genes
AnswerD.
Additive gene action
Answer: Option C
Solution
Answer: Option C
Solution:
The dihybrid ratio 9 : 3 : 4 indicates Supplementary gene interaction.Supplementary genes are genes that both contribute to a single characteristic, where one gene can mask the effect of the other.
Two independent dominant genes interact to produce a phenotypic expression different from that produced by either gene alone.
