5. The human ABO blood groups are A, B, AB and O. They are determined by a single gene with multiple alleles. Iª and 1³ alleles are codominant, but both these alleles are dominant to the lº allele. In a maternity ward, the identities of four babies became accidentally mixed up. The ABO blood groups of the babies were discovered to be O, A, B and AB. The ABO blood groups of the four sets of parents were determined and are shown in the table below. Complete the table to match each baby to its parents by indicating: the parental genotypes, using the symbols IA, IB and 10; the blood group of the baby which belongs to each set of parents. parental blood groups O and O AB and O parental genotypes baby blood group

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
