Question

In horses, a straight coat (S) is dominant over a curly coat (s). A breeder has a female horse that is heterozygous for coat texture. Which type of male horse should he breed her with for the greatest likelihood of producing a curly coated foal?




A a male horse that is homozygous recessive for coat texture
B a male horse that is heterozygous recessive for coat texture
C a male horse that is homozygous dominant for coat texture
D a male horse that is heterozygous dominant for coat texture

Answer 1

help pls

Answer 2

D (:

Answer 3

So if I understand the Mare has the ability of either coat texture?

Answer 4

If the Mare has the ability of either and the desired outcome is a curly coated foal I would say C... could be wrong but we raised horses and know that the foal is always (in most cases) going to get about 80% of the mare's color, disposition, etc.
Has to do with color but hopefully it will help with the curly coat... basically the same concept.
t = Hetrozygous Coloured
TT= Homozygous coloured
tt = plain

so if the foal get the T gene from the coloured stalion it will be coloured if it gets the t it will be plain, as the mares are plain they cannot get the T (coloured) gene from her.

As my mare was hetrozygous coloured same as the stallion I had a 75% chance coloured and 25% Plain

Tt = mare
Tt = Stallion

So combinations could be Tt tT TT or tt where T is present = coloured so three occurances of T and one without T so 75% coloured and 25% plain.
