1. If D is a dominant allele for the Rh factor, what will be the genotypic ratio for a monohybrid heterozygous cross of (Dd x Dd)? What will the phenotypic ratio be?
2. What is meant by Independent Assortment?
3. What accounts for the four phenotypes in the ABO blood grouping system?
4. What antibodies are present in a person with type AB blood (neglecting the Rh factor).
