**ABO Blood Type Genetics and Dominance in Hair Traits: Educational Insights** **Question 9:** A child has type AB blood. Which of the following statements is true? - **A)** One of the parents could be type O - **B)** One of the parents could be A - **C)** One of the parents could be type B - **D)** One of the parents could be AB **Question 10:** Short hair (S) is dominant to long hair (s). If a short-haired animal of unknown origin is crossed with a long-haired animal and they produce one long-haired and one short-haired offspring, this would indicate that: - **A)** The short-haired animal was pure-breeding. - **B)** The short-haired animal was not pure-breeding. - **C)** The long-haired animal was not pure-breeding. - **D)** The long-haired animal was pure-breeding. **Explanation:** **Blood Type Inheritance (Question 9):** The ABO blood type system is governed by multiple alleles: A, B, and O. The combination of these alleles dictates the blood type. - Type AB blood means the individual has one A allele and one B allele. - For a child to have type AB blood, one parent must have at least an A allele and the other a B allele. Therefore, the true statements are: - **B)** One of the parents could be A. - **C)** One of the parents could be type B. - **D)** One of the parents could be AB. Type O (alleles OO) parent cannot contribute an A or B allele, making option A incorrect. **Dominance in Hair Traits (Question 10):** Hair length in this genetic context follows Mendelian inheritance, with short hair (S) being dominant over long hair (s). - If two animals (one short-haired of unknown genotype and one long-haired) produce offspring that include both phenotypes, we can infer the genotypes. - The appearance of a long-haired offspring (ss) means the short-haired parent must have contributed an 's' allele, indicating that it is heterozygous (Ss). Thus, the correct statement is: - **B)** The short-haired animal was not pure-breeding (as it must have been Ss to produce long-haired offspring). This basic understanding of inheritance usefully demonstrates the principles
