Question

• How does Epistasis affect the outcome of genes?

Answer 1

The epistasis means the outcome of one gene which is dependent on the presence or absence of one or more genes like it is a type of gene interactions when one gene mask or modified the expression of another gene at distinct locus.

Any gene that mask the expression of another non alleic gene is epistatic gene and the suppressed gene is called hypostatic.

Eustatic can affect the expression by affecting the expression of mRNA or protein of onther gene's product as for example,suppose purple colour is developed by enzyme B from red product and red product is produced from 2hite product in presence of enzyme A and white product is the primary .then if enzyme A is not present then purple product will not be produced because enzyme A is necessary for converting Red product to purple product.

So, may the one gene's product can be TRANSCRIPTION factor of onther gene 's or some thing that helps in expression of another gene's expression
