The genotype of the red fish if it produces 50% red progeny on mating with a gray fish, provided that the red color is a “dominant trait,” and gray color is a “recessive trait.” Introduction: A dominant allele is the one that expresses itself even when present in the heterozygous or the homozygous state. However, a recessive allele is expressed in the homozygous state only. A test cross is a cross between the individual of an unknown genotype and an individual with a recessive homozygous genotype. Test cross can help us to identify the genotype of the unknown individual.
