Waxy endosperm (wx), shrunken endosperm (sh), and yellow seedling (v) are encoded by three recessive genes in corn that are linked on chromosome 5.
A corn plant homozygous for all three 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 three-point testcross.
The progeny of the testcross are:
wx | sh | V | 84 |
Wx | Sh | v | 95 |
Wx | Sh | V | 3479 |
wx | sh | v | 3478 |
Wx | sh | V | 1512 |
wx | Sh | v | 1525 |
wx | Sh | V | 292 |
Wx | sh | v | 284 |
What is the genetic distance between Wx and V?
