Given below is a table showing the genotypes of blood groups in the human population. S.no Genotype Phenotype 1. I A I O A-Phenotype for Y 2. I B I O B-Phenotype for Z 3. I A I B AB 4. X O Name the pattern of inheritance exhibited by the phenotypes Y and Z in the table.

See the answer table given below S.no Genotype Phenotype 1. I A I O A (Y) 2. I B I O B (Z) 3. I A I B AB 4. ii O Y: The allele I A is dominant over i and hence, the phenotype is A group. So it follows law of dominance. Z: The alleles I B is dominant over I O hence the phenotype is B. It also follows the same patterns of inheritance.
