MCQs on Gene Interactions - Genetics mcq - Most Important Questions
This Video contains most important questions about Gene Interactions.Genetic interaction is the set of functional association between genes. One such relationship is epistasis, which is the interaction of non-allelic genes where the effect of one gene is masked by another gene to result either in the suppression of the effect or they both combine to produce a new trait (character).
Complementary genes:
Complementary genes are genes that both contribute to a single characteristic, where both genes can mask the effect of the other. You may also think of complementary genes as any instance in which dominant forms of both genes are required for the dominant characteristic to be seen.
Supplementary genes:
Supplementary genes are genes that both contribute to a single characteristic, where one gene can mask the effect of the other. You may also think of supplementary genes in terms of one gene producing a characteristic and the second as only being able to 'supplement' this characteristic.
Epistatic genes:
A gene is said to be epistatic when its presence suppresses the effect of a gene at another locus. Epistatic genes are sometimes called inhibiting genes.
Hypostatic gene:
A hypostatic gene is one whose phenotype is altered by the expression of an allele at a separate locus, in an epistasis event.

Question no. 32: Phenotypic ratio 15:1 is found in Duplicate gene. It's not inhibitory gene. 13:3 ratio is obtained for inhibitory gene...

[@SchoolofBiologyy]

you are very true. thanks for correction

hi

[@Ruby-ni3ll]

Zoology Assistant professor k PYQ bhi solve kijiye please har states ke

[@essaraja7227]

Please explain how to find no: of genes

[@Shweta_33]

👌👌🙏

[@tanishkavarshney7988]

Que no. 32 is wrong
Bcz 15:1 Is for duplicate gene and also called double Dominant epistasis .....

[@mamtanegi9172]

Question no 3 is wrong 3:3:4 is recessive epistatic
