PLEASE HELP!!
You need to do a 3 point mapping experiment in grain. The three
genes are
autosomal, and the mutant traits are all homozygous recessive. My
three genes are:
Acorn (ac)
Barley (ba)
Candy (cn)

A female plant is heterozygous for all
three traits, and she is crossed with a male that is
homozygous recessive for all three traits. The
results of the cross are as follows:

Mutant Phenotypes



Number Observed
a) Given the results of the cross, what gene is in the
middle?
b) What are the map distances between each gene? Please be
specific which genes the distances correspond to... What is the
inference?
