Answer:
The expected phenotypic ratio of offspring from a hybrid mare and stallion in Biology.
Explanation: The expected phenotypic ratio of offspring produced when a hybrid mare and hybrid stallion are mated can be determined using a Punnett square. The genotype of the mare and stallion should be known. The possible genotypes of the offspring can then be determined, and the phenotypic ratio can be calculated based on the expression of different alleles.
Let's assume that the mare is hybrid (Hh) and the stallion is also hybrid (Hh). By cross-mating these two individuals, we can create a Punnett square to determine the possible genotypes and phenotypes of offspring. In this case, the expected phenotypic ratio of the offspring would be 1:2:1, with 1 offspring having the homozygous dominant genotype (HH), 2 offspring having the heterozygous genotype (Hh), and 1 offspring having the homozygous recessive genotype (hh).
The phenotypes would depend on the expression of the allele, for example, if H represents a black coat color and h represents a white coat color, the phenotypic ratio would translate to 1 offspring with a black coat, 2 offspring with a black and white spotted coat, and 1 offspring with a white coat.
