According to chance what fraction of their children will have dimples?
To determine the fraction of children that will have dimples according to chance, you first need to know the probability of inheriting dimples from both parents.
Dimples are considered a dominant trait, which means that if at least one parent has dimples, there is a chance that their children will also have dimples. If both parents have dimples, the chances increase further.
To calculate the fraction of children expected to have dimples, you need to consider the probability of both scenarios: when one parent has dimples and when both parents have dimples.
1. If one parent has dimples:
- If one parent has dimples (dominant trait), the probability of passing it on to their child is 1 (100% chance).
- If the other parent does not have dimples (recessive trait), the probability of passing it on is 0.
- The combined probability is 1 x 0 = 0.
2. If both parents have dimples:
- If both parents have dimples, each parent can pass down the trait with a probability of 1 (100% chance for both).
- The combined probability is 1 x 1 = 1.
Now, to calculate the fraction of children with dimples, you need to consider the possible combinations of parents having or not having dimples:
- If both parents have dimples:
Probability of children having dimples = 1 (100% chance)
- If one parent has dimples and the other does not:
Probability of children having dimples = 0 (0% chance)
Assuming there are only these two scenarios, the fraction of children expected to have dimples would be 1/2 or 0.5.
Please note that these calculations are based on simplified Mendelian genetics and assume that dimples are determined by a single gene with simple dominant and recessive inheritance patterns. In reality, there might be other factors and complexities involved.
