In Cucurbita, W is epistatic over Y and y gene normally responsible for yellow and green colour fruits. It produces white flowers. What is the ratio of fruits in the progeny of cross WwYy xx wwYy ?

In Summer Sqash, the fruit colour can be white, yellow and green. The appearance of white colour is due to a dominant gene W. The latter is

Assertion : Variety of fruit colours in Cucurbita pepo is result of recessive epistasis Reason : In recessive epistatsis, a recessive gene at one locus engances the expression of another gene, at a diferent locus.

In Pisum, yellow seed colour (Y) is dominant over green (y), and round shape of seed (R ) is dominant over wrinkled (y). Consider that these two pair of genes assort independently, then (i) What proportion of the offsprings from the cross the cross YyRr xx yyrr would expected to have yellow-seeded trait ? (ii) From the cross Yyrr xx Yyrr , how many will be pure yellow-wrinkled plants in the resulting generation ?

A gene has two alleles B and b. B is responsible for the expression of character x . b. is responsible for the expression of character y. B. is completely dominant over b. Another gene A is epistatic on gene B. When A is in the dominant condition it suppress the expression of B and b and gives rise to character z.In recessive condition (allele a) allows expression of B and b. When an organism with genotype AaBb is crossed with another organism with genotype AbBb, the ratio of characters x,y and z seen in its offsprings is
