1. list the distances between each pair of genes: (you figured this out in parts 1-3) beak color (y) and tail-feather length(l): beak color(y)and feather color (b): tail-feather length(l)and feather color(b):

Explanation: The question seems incomplete. However my response might assist you. It seems the last three questions are referring to everything you just worked on. So all you would have to do is refer to your previous answers. Note that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".

1.List the distances between each pair of genes:

beak color and tail-feather length: 20 MU

beak color and feather color: 16 MU

tail-feather length and feather color: 4 MU

2.Which two alleles are the farthest apart?

(the one that is 20 MU apart) Y and L

3.Which two alleles are the closest together?

(the ones that are 4 MU apart) L and B

True or False: The diagram shows the correct genetic map for these three alleles on one chromosome.
