Answer

B

Explanation

Fruit colour in squash is an example of dominant epistasis in which the dominant gene (epistatic gene) masks the effect of other gene (recessive hypostatic gene).
Squash fruit appear white due to the epistatic effect of 'W' allele (white colour) over 'G' allele (green colour).
