Hospitals typically have excellent measures in place to prevent mix-ups, but one baby was not so lucky. The hospital has narrowed down that baby Anthony must belong to one female and one male in the below list, although the hospital also does not know which individuals are couples. Find Anthony’s parents!
Possible Parents:
\table[[\table[[Natasha (female)],[Blood Type: B]],\table[[Adrianne (female)],[Blood Type: AB]],\table[[Rafael (male)],[Blood Type: O]],\table[[Joshua (male)],[Blood Type: AB]]]]
\table[[Baby Anthony,\table[[13. ?Anthony’s],[genotype:]],\table[[14. ?His mother from],[above list (list name):]],\table[[16. ?His father from],[above list (list name):]]],[,,,],[Blood Type: 0,,,]]
Draw the Punnett Square below that shows the cross between the mother and father you selected.
What is the percent chance in the Punnett square that you drew of having an ?? ?baby? ?
Can a baby that has blood type ???? ?have one parent that is type ?? ? ?Why or why not? If it is difficult to explain, try explaining with a Punnett Square diagram.
The Correct Answer and Explanation is :
To determine Baby Anthony’s parents, we need to analyze the blood types of the potential mothers and fathers. Baby Anthony has blood type O, which means he must have inherited an O allele from each parent. This is because blood type O is recessive, and a person with blood type O has the genotype OO.
Step 1: Determine the Genotypes of Potential Parents
- Mothers:
- Natasha (Blood Type B): Her genotype could be either BB or BO.
- Adrianne (Blood Type AB): Her genotype is AB.
- Fathers:
- Rafael (Blood Type O): His genotype is OO.
- Joshua (Blood Type AB): His genotype is AB.
Step 2: Identify Possible Parent Combinations
- Mother: Natasha (Blood Type B)
- Father: Rafael (Blood Type O)
- Mother’s possible alleles: B or O
- Father’s alleles: O and O
- Punnett Square: O O B BO BO O OO OO
- Possible Offspring Genotypes: BO (Blood Type B) or OO (Blood Type O)
- Conclusion: This combination can produce a child with blood type O.
- Mother: Adrianne (Blood Type AB)
- Father: Rafael (Blood Type O)
- Mother’s alleles: A and B
- Father’s alleles: O and O
- Punnett Square: O O A AO AO B BO BO
- Possible Offspring Genotypes: AO (Blood Type A) or BO (Blood Type B)
- Conclusion: This combination cannot produce a child with blood type O.
- Mother: Natasha (Blood Type B)
- Father: Joshua (Blood Type AB)
- Mother’s possible alleles: B or O
- Father’s alleles: A and B
- Punnett Square: A B B AB AB O AO BO
- Possible Offspring Genotypes: AB (Blood Type AB), AO (Blood Type A), or BO (Blood Type B)
- Conclusion: This combination cannot produce a child with blood type O.
- Mother: Adrianne (Blood Type AB)
- Father: Joshua (Blood Type AB)
- Mother’s alleles: A and B
- Father’s alleles: A and B
- Punnett Square: A B A AA AB B AB BB
- Possible Offspring Genotypes: AA (Blood Type A), AB (Blood Type AB), or BB (Blood Type B)
- Conclusion: This combination cannot produce a child with blood type O.
Step 3: Conclusion
The only combination that can produce a child with blood type O is Natasha (Blood Type B) and Rafael (Blood Type O). Therefore, Baby Anthony’s parents are Natasha and Rafael.
Punnett Square for Natasha (Blood Type B) and Rafael (Blood Type O):
| O | O | |
|---|---|---|
| B | BO | BO |
| O | OO | OO |
Probability of Baby Anthony’s Blood Type:
- Genotypes:
- Mother (Natasha): BB or BO
- Father (Rafael): OO
- Possible Offspring Genotypes:
- If Natasha is BB: BO (Blood Type B)
- If Natasha is BO: BO (Blood Type B) or OO (Blood Type O)
- Conclusion: There is a 50% chance of Baby Anthony having blood type O.
Can a Baby with Blood Type O Have One Parent with Blood Type O?
Yes, a child with blood type O can have one parent with blood type O. For a child to have blood type O, they must inherit an O allele from each parent. If one parent is blood type O (OO), they can only pass on an O allele. The other parent must also carry an O allele, either as their only allele (blood type O) or as a recessive allele (heterozygous blood type B or A). Therefore, a child with blood type O can have one parent with blood type O, but the other parent must carry at least one O allele.
Punnett Square for Blood Type O Inheritance:
| O | O | |
|---|---|---|
| O | OO | OO |
| O | OO | OO |
In this Punnett square, both parents are blood type O (OO). All offspring will inherit one O allele from each parent, resulting in blood type O.
In summary, Baby Anthony’s parents are Natasha and Rafael, and there is a 50% chance of a child inheriting blood type O from this couple. Additionally, a child with blood type O can have one parent with blood type O, provided the other parent carries at least one O allele.
