Question

Start with the P generation with the following genotypes (AA x aa). Based on classical Mendelian inheritance, how will a cross between two homozygous parents, one dominant and one recessive, influence future generations?

Answer 1

Well the kids would be hetero and it would just depend on who they cross with after that

Answer 2

Therefore 100% of the children will be heterozygous.

Step-by-step explanation:

Hello!

Let's solve this!

According to Mendelian genetics, if one of the parents is a homozygous dominant (AA) and the other parent is a homozygous recessive (aa), the children will have:

The combinations would be:

Aa (with the first A and the first a)

Aa (with the first A and the second a)

Aa (with the second A and the first a)

Aa (with the second A and the second a)

Therefore 100% of the children will be heterozygous.

Then, they will depend on the genes of the person they cross.
