Station 6: Multiple Alleles
Kylie Jenner and Travis Scott had baby Stormi, but they don't know
her blood type. Kylie is type O and Travis is Type AB. What are the
possible blood types that Stormi could be?
If they have another baby, but Travis thinks its not his. The baby has
type O blood. Can Travis be the father?



Answer :

In this scenario involving multiple alleles for blood types, let's break down the possibilities for Stormi's blood type and then address the paternity question.

1. Possible blood types for Stormi:
- Kylie Jenner is blood type O, which means she has two "O" alleles.
- Travis Scott is blood type AB, which means he has an "A" and a "B" allele.
- When it comes to blood type inheritance:
- Alleles for blood type A and B are dominant over O.
- Type O is recessive, needing two "O" alleles to express the O blood type.
- Since Travis has one A and one B allele, he can pass on either an A or a B allele to the baby.
- Stormi could have blood type A, B, or AB since Kylie can only pass on an "O" allele.

2. Paternity question:
- If Kylie is blood type O and Travis is type AB, and they have a baby with blood type O, it would be impossible for Travis to be the father.
- This is because for the baby to have blood type O, it would need to inherit an "O" allele from both parents. Travis can only pass on an A or B allele, not an O allele.
- Therefore, based on blood type compatibility, Travis cannot be the father of a child with blood type O if he is blood type AB.

In conclusion, Stormi could have blood type A, B, or AB, considering the parents' blood types. Additionally, if a subsequent child between Kylie and Travis has blood type O, it would not be biologically possible for Travis to be the father based on the principles of blood type inheritance.
