using the punnet square one trait is Dd and the other id dd.

1) does the mother or father in a have dimples

b) what percentage of children are likely to have dimples

i think for a: it is the father because of the D so that it dominant and
b:50 because two of the kids will have Dd

To determine which parent has the trait for dimples, we can look at the Punnett square. In this case, one parent is Dd and the other is dd.

1) For the question "Does the mother or father have dimples?" we can use the Punnett square to determine the possible combinations when crossing the traits.
Dd x dd:

| | d | d |
|----|----|----|
| D | Dd | Dd |
| d | dd | dd |

From the Punnett square, we can see that both parents can pass on the 'd' allele to their child, which means either the mother or father could have dimples. So we cannot definitively determine whether the mother or father has dimples based on this information alone.

2) To determine the percentage of children likely to have dimples, we can count the number of offspring with the Dd genotype from the Punnett square.

From the Punnett square, we can see that two out of the four possible combinations result in the Dd genotype (i.e., Dd, Dd). Therefore, there is a 50% chance that a child will have dimples.

So to answer your question, we cannot determine which parent has dimples based on the given information, and there is a 50% chance that a child will have dimples.
