The offspring produced from a marriage have only \(\mathrm{O}\) or \(\mathrm{A}\) blood groups. Of the genotypes given below, the possible genotypes of the parents would be:
1 \(I^{A} I^{o}\) and \(I^{o} I^{o}\)
2 \(I^{A} I^{A}\) and \(I^{O} I^{O}\)
3 \(I^{A} I^{O}\) and \(I^{O} I^{O}\)
4 \(I^{A} I^{A}\) and \(I^{A} I^{O}\)

When dominant and recessive alleles express themselves together, it is called
1 Pseudodominance
2 Dominance
3 Co-dominance
4 Amphidominance
Explanation:
In Co-dominance, both the alleles dominant or recessive of a gene express themselves in theheterozygotes. Phenotypes of both the parents appear in \({F_1}\) hybrid rather than the intermediate phenotype.

Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group, respectively. What would be the genotype of both mother and father?
1 Mother is homozygous for ‘A’ blood group and father is heterozygous for ‘B’
2 Mother is heterozygous for ‘A’ blood group and father is homozygous for ‘B’
3 Both mother and father are heterozygous for ‘A’ and ‘B’ blood group, respectively
4 Both mother and father are homozygous for ‘A’ and ‘B’ blood group, respectively
Explanation:
Possible genotype of parents are; IAi (A blood group) and IBi (B blood group) and phenotype of offspring is ii (O blood group).

Four children belonging to the same parents have the following blood groups: \(\mathrm{A}, \mathrm{B}, \mathrm{AB}\) and \(\mathrm{O}\). Hence, the genotypes of the two parents are:
1 Both parents are homozygous for ' \(\mathrm{A}\) ' group
2 One parent is homozygous for ' \(\mathrm{A}\) ' and another parent is homozygous for ' \(\mathrm{B}\) '
3 One parent is heterozygous for ' \(\mathrm{A}\) ' and another parent is heterozygous for ' \(\mathrm{B}\) '
4 Both parents are homozygous for ' \(\mathrm{B}\) ' group
Explanation:
In men, ABO blood group is best example of multiple allelism. The four children of blood group. A, B, AB and O can be born only if both the parents are heterozygous for A and B, which means the genotype of one parent is \({l^A}l\) and of other is\({l^B}l\),
