Question

determine the coefficient of coincidence and the interference among these genes

1. In corn, waxy endosperm (wx), shrunken endosperm (sh), and yellow seedlings
(v) are encoded by 3 recessive genes located on chromosome 5. A corn plant
homozygous for all 3 recessive alleles is crossed with a plant homozygous for all
the dominant alleles. The resulting F1 are then crossed with a plant homozygous
for the recessive alleles in a 3-point testcross. The progeny of the testcross are:
