Gene mapping for beak color and feather length in biology what is this
just olya [345]
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?

These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall 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

The ears, feet and tail of north american mammals are often smaller in northern species than they are in southern species. Expla
alukav5142 [94]
This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>
