Nonallelic genes having similar phenotypic effect, interact to produce a different trait and a ratio 9 : 7 in F2 generation are
The correct option is A Complementary genes
A.Epistatic
gene - A gene masks the action of another gene is termed as epistatic gene. In
the F2 generation 12:3:1 ratio.
B.Hypostatic
gene – A gene whose effect are masked is by another gene is called Hypostatic
gene. In the F2 generation 12:3:1 ratio.
C.Supplementary
gene – genes which include two pairs of non-allelic genes. Both of
them are involved in affecting the same character. Out of the non-allelic genes,
one gene is dominant and can express by itself. Second gene is
also dominant but expresses only when it is supported by the presence of the
first gene.In the F2 generation 9:3:4 ratio.
D.Complementary
gene – Two genes present on separate loci that interact together to produce a
dominant phenotype is called Complementary gene. In the F2 generation
9:7 ratio.
So,
the correct option is ‘Complementary gene’.
