The possible phenotypes of the calves for each cow depend on the genetic makeup of the parents. The phenotype is the observable characteristic of an individual, determined by environmental influences and genetic makeup. The genetic makeup of an individual is called the genotype, which is the foundation for specific traits.

The search results provide some examples of possible phenotypes for different cows. For instance, if a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), the offspring will have the genotype Rr and the phenotype roan. Another example is that if we mate an homozygous bull with two horned alleles (pp) with an homozygous cow with two polled alleles (PP), the calf will be heterozygous Pp and its phenotype will be polled.

In summary, the possible phenotypes of the calves for each cow depend on the genetic makeup of the parents. The phenotype is the observable characteristic of an individual, determined by environmental influences and genetic makeup. The genotype is the genetic makeup of an individual, which is the foundation for specific traits.
