Dear student,
Please find below the solution to the asked query

Neither the assertion not the reason is true.

Variety of fruit colours in (white, yellow and green) Cucurbita pepo is a result of dominant epistasis.

In recessive epistasis, the recessive gene 'a' of one gene locus hides or masks the expression of another gene 'b' of a different locus to express itself phenotypically.
