If a man of M blood group marries a woman of N blood group, all their children will have.
Correct answer: D. MN blood group
- A. M blood group
- B. N blood group
- C. O blood group
- D. MN blood group
Explanation
There are three general phenotypes; M,N and MN. M phenotype has antigen M which is produced by gene LM. N phenotype has antigen N that is produced by its allele LN. MN phenotype has both M and N antigens, simultaneously produced by their alleles LM and LN

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
