Horses have a gene for coat color. The dominant allele gives a brown coat while the recessive allele gives a white coat. A breeder is crossing a purebred brown horse with a hybrid brown horse. What are the possible phenotypes of the offspring?

they will all be brown horses but only two will have both dominant alleles, the other two will each have one recessive

idk

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
