Answer:
When two individuals who are heterozygous for the ABO blood group system have children, they can pass on either the A or B allele to their offspring. The possible blood types for their children depend on which alleles they inherit from each parent.
The ABO blood group system involves three alleles: A, B, and O. Each individual inherits two alleles, one from each parent. The possible combinations for the offspring of two heterozygous individuals (with genotype AO and BO) are as follows:
Therefore, the possible blood types for the children of two heterozygous individuals (AO and BO) are A, B, AB, and O.
Explanation:
AO x BO:
A allele from the first parent and B allele from the second parent, resulting in AB blood type.
A allele from the first parent and O allele from the second parent, resulting in A blood type.
O allele from the first parent and B allele from the second parent, resulting in B blood type.
O allele from both parents, resulting in O blood type.
BO x AO:
B allele from the first parent and A allele from the second parent, resulting in AB blood type.
B allele from the first parent and O allele from the second parent, resulting in B blood type.
O allele from the first parent and A allele from the second parent, resulting in A blood type.
O allele from both parents, resulting in O blood type.
