    Explanation <\/strong><\/h3>\n\n\n\n

    Human blood types are determined by the ABO gene, which comes in three alleles: A, B, and O. Every person inherits one allele from each parent, leading to four main blood types: A, B, AB, and O. Blood type A can be AA or AO, type B can be BB or BO, type AB is AB, and type O is OO.<\/p>\n\n\n\n

    In this scenario, Jack is heterozygous for type A, meaning his genotype is AO. Jill is heterozygous for type B, meaning her genotype is BO. To determine the possible blood types of their children, we use a Punnett square\u2014a diagram that predicts the genotypes of offspring based on the alleles of the parents.<\/p>\n\n\n\n

    By placing Jack\u2019s alleles (A and O) on one side of the square and Jill\u2019s alleles (B and O) on the other, we calculate all combinations: AB, AO, BO, and OO. Each box in the Punnett square represents a 25% chance of that genotype. This results in four possible blood types:<\/p>\n\n\n\n

      \n
    • AB (from A and B)<\/strong><\/li>\n\n\n\n
    • A (from A and O)<\/strong><\/li>\n\n\n\n
    • B (from B and O)<\/strong><\/li>\n\n\n\n
    • O (from O and O)<\/strong><\/li>\n<\/ul>\n\n\n\n

      Thus, their children could have any of the four blood types, each with an equal probability.<\/p>\n\n\n\n

      The AB genotype<\/strong> can receive blood from any type (universal recipient) because it has both A and B antigens and no antibodies against A or B. The O genotype<\/strong> is the universal donor because it has no A or B antigens on the red cells, so it won\u2019t trigger an immune response in recipients of any blood type.<\/p>\n\n\n\n

      Understanding inheritance patterns like these helps explain genetic probability and is vital in medicine, especially in transfusions and organ transplants.<\/p>\n\n\n\n
