Probability of Inheritance
- Albinism is an autosomal recessive trait, which means that it is caused by a mutation on a non-sex chromosome (autosome) and two copies of the mutated gene are needed to express the trait.
- Each parent in this case has one normal copy of the gene and one mutated copy (carrier).
- The chance of passing on the mutated gene to their child is 50% for each parent.
- The probability of having an albino child is only possible if both parents pass on their mutated copy of the gene to their child.
Punnett Square
- A Punnett square can be used to determine the probability of the couple's second child being albino.
- The Punnett square shows the four possible combinations of the parents' genes that can be passed on to their child.
| | Normal | Carrier |
|---|--------|---------|
| C | 1 | 1 |
| c | 1 | 1 |
- The first child was albino, which means that both parents must have passed on their mutated copy of the gene (cc).
- The Punnett square shows that for the second child, there is a 25% chance of inheriting two copies of the mutated gene (cc) and being albino.
- Therefore, the probability of the couple's second child being albino is 25%, or option A.
