A child of O-group has B-group father. The genotype of father will be:
Correct answer: D. IBIO
- A. IOIO
- B. IBIB
- C. IAIB
- D. IBIO
Explanation
The child has an O-group, indicating a genotype of IOIO, which means both parents must contribute an IO allele. Since the father has a B-group blood type, his genotype must be IBIO to provide the necessary IO allele. Other options do not fit because they either can't produce an O-group child or don't match the father's blood type.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.

Mendel studied inheritance of seven pairs of traits in Pea which can have 21 possible combinations. If you are told that in one of these combinations, independent assortment is not observed in later studies, your reaction will be:
