To create the Punnett squares, we need to know the possible genotypes for each of the fathers based on their blood type. The genotypes for blood types are as follows:
- Type A: AA or AO
- Type B: BB or BO
- Type AB: AB
- Type O: OO
Using this information and the mother's genotype (Type A heterozygous), we can create the following Punnett squares for each potential father:
1. Sammy the player (Type O)
| | O | O |
|----|----|----|
| A | AO | AO |
| A | AO | AO |
Possible genotypes of offspring: AO (Type A heterozygous)
2. Guy at the club (Type AB)
| | A | B |
|----|----|----|
| AB | AB | AB |
| AB | AB | AB |
Possible genotypes of offspring: AB (Type AB)
3. The waiter (Type A homozygous)
| | A | A |
|----|----|----|
| A | AA | AA |
| A | AA | AA |
Possible genotypes of offspring: AA (Type A homozygous)
4. The cable guy (Type B homozygous)
| | B | B |
|----|----|----|
| A | AB | AB |
| A | AB | AB |
Possible genotypes of offspring: AB (Type AB)
Based on the Punnett squares, the potential fathers who could be the biological father of the baby are Guy at the club and The cable guy, as they both have the potential to produce offspring with Type B blood, which is the blood type of the baby. Sammy the player and The waiter are not possible fathers, as their potential offspring would have Type A blood.
