Hey, everyone. Let's take a look at this question together which of the following statements best describes the inheritance pattern of a bo blood types. Is it answer choice? A abo blood types exhibit codominance, answer choice. Babo blood types exhibit incomplete dominance answer choice. Cabo blood types exhibit dominant inheritance or answer choice. Dabo blood types exhibit recessive inheritance. Let's work this problem out together to try to figure out which of the following answer choices best describes the inheritance pattern of a bo blood types. So in order to solve this question, we have to recall what we have learned about the different inheritance patterns to determine which best explains a bo blood types. And we can recall that in the case of a bo blood types, the A and B alleles are codominant, which we know that codominance is a genetic inheritance pattern where both alleles of a gene are expressed equal in the phenotype of a heterozygote, which tells us that if an individual inherits one A allele and one B allele, they will express both A and B antigens on their red blood cells. So looking at our answer choices, we can identify answer choice A as the correct answer since a bo blood types do exhibit codominance and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
