hi could you please help with the following question:
In humans, free ear lobes is dominant to attached ear lobes. A male who is pure breeding for free ear lobes marries a woman who is pure breeding for attached ear lobes. What type of ear lobes will the children. (Including a plunnet square in the answer).
Man is FF, woman is aa.

Sure, I can help with that!
To determine the types of ear lobes their children will have, we can use a Punnett square.
First, let's assign the letter "F" to represent the dominant trait of free ear lobes, and the letter "A" to represent the recessive trait of attached ear lobes.
Since the male is pure breeding for free ear lobes, his genotype will be FF. On the other hand, the female is pure breeding for attached ear lobes, so her genotype will be AA.
To create the Punnett square, we will combine the alleles from each parent. Each parent will contribute one allele to each potential child.
| F | F |
--------------
A | AF| AF|
--------------
A | AF| AF|
From the Punnett square, we can see that all the children will have the genotype AF, which means they will have free ear lobes.
So, the children will have free ear lobes since the dominant trait of free ear lobes (F) is expressed in all the combinations.
I hope that helps! Let me know if you have any further questions.
