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?
What is the genetic distance between Sh and V?
What is the interference among these genes?
im confused on how to determine the map unit distance between genes.
