It is only observed in reptiles and teleost fish. In Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair color (b), and the allele for polled (P), or lacking horns, is dominant over the allele for having horns (p). If both parents are heterozygous in a monohybrid cross, the offspring will have a phenotypic ratio of 3:1. Use a Punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). The phenotypic ratio is the relationship between the number of offspring who will inherit a certain characteristic or a set of traits. When a homozygous dominant individual is crossed with a homozygous recessive individual, the offspring produced will have the heterozygous genotype and show the dominant phenotype. An offsprings genotype is the result of the combination of genes in the sex cells or gametes (sperm and ova) that came together in its conception.One sex cell came from each parent. c. AA Aa.
