Four babies are born in a hospital and are mixed up. Based on the blood type and hairline, match the baby to its parents. Type A blood and Type B blood are codominant and type O is recessive. Widow's peak is dominant to a straight hairline. Each baby has the following phenotypes: Baby A B blood, widows peak Baby B = B blood, straight hairline Baby C=AB blood, straight hairline Baby D= O blood, straight hairline The phenotypes of the parents are as follows: Ms. Smith: A blood, widows peak Mr. Smith: B blood, straight hairline Ms. Jones: O blood, widows peak Mr. Jones: O blood, widows peak Ms. Black: AB blood, widows peak Mr. Black: O blood, straight hairline Ms. Green: B blood, straight hairline Mr. Green: B blood, straight hairline shape

Question
**Title:** Determining Parentage Through Blood Type and Hairline Phenotypes **Text:** Four babies are born in a hospital and are mixed up. Based on the blood type and hairline, match the baby to its parents. Type A blood and Type B blood are codominant. Widow’s peak is dominant to a straight hairline. Each baby has the following phenotypes: - **Baby A:** B blood, widow's peak - **Baby B:** B blood, straight hairline - **Baby C:** AB blood, straight hairline - **Baby D:** O blood, straight hairline The phenotypes of the parents are as follows: - **Ms. Jones:** O blood, widow's peak - **Mr. Jones:** O blood, widow's peak - **Ms. Black:** AB blood, widow's peak - **Mr. Black:** O blood, straight hairline - **Ms. Smith:** B blood, straight hairline - **Mr. Smith:** B blood, straight hairline - **Ms. Green:** B blood, straight hairline - **Mr. Green:** B blood, straight hairline **Analysis:** - Consider the genetic rules of dominance for hairline and codominance of blood types in matching each baby with their respective parents. - Widow's peak is a dominant trait, so parents without a widow's peak cannot have a child with a widow’s peak. - For blood type, type O is recessive, so at least one parent must contribute an O allele for a child to have O blood. **Purpose:** This exercise helps understand genetic inheritance and how phenotypes are determined based on parental genotypes, useful in both educational and forensic contexts.
