Imagine the autosomal dominant cb allele produces black coat color in dogs, and the recessive cw allele produces a white coat color. the cb allele is also recessive for lethality; pups with the cbcb genotype die well before birth, and their remains are resorbed by the mother’s uterus. imagine you cross a heterozygous black male dog with a heterozygous black female. what ratio of genotypes and phenotypes do you expect to see in the f1 offspring? if more than one genotype produces the same phenotype, list all the genotype/phenotype combinations separately.
