In horses, coat color is determined by a genetic locus in which the white allele is dominant to the colored allele, but when the embryo is homozygous for the white allele it is fatal (death in utero). If two white horses mate, then what proportion of the offspring will have white coats? O 1/2 1/3 O 2/3 O 3/4 O 1/4

Three coat-color patterns that occur in some breeds of horses aretermed cremello (beige), chestnut (brown), and palomino (goldenwith light mane and tail). If two palomino horses are mated, theyproduce about 1/4 cremello, 1/4 chestnut, and 1/2 palomino offspring. In contrast, cremello horses and chestnut horses breed true.(In other words, two cremello horses will produce only cremellooffspring, and two chestnut horses will produce only chestnut offspring.) Explain this pattern of inheritance.
