In trolls three eyes "E" are dominant to two eyes "e". A heterozygous mom is crossed with a two eyed dad. What is the genotype of the mother?

Does this mean in a punnett squer the mom is Ee while the dad is ee because two eyed is recessive? So mom would be heterozygous dominant?

Bingo!!!!!

Heterozygous means different genes.

Ee x ee
I
I
V
2 Ee
2 ee

Yes, in this scenario, the uppercase "E" represents the dominant allele for three eyes, while the lowercase "e" represents the recessive allele for two eyes. If a heterozygous (Ee) mother is crossed with a two-eyed (ee) father, we can deduce the genotype of the mother based on the principle of Mendelian inheritance.

To start, let's create a Punnett square to determine the possible genotypes of the offspring. We'll place the mother's alleles on the top and the father's alleles on the side:

| E | e |
-------------------
E | EE | Ee |
e | Ee | ee |

In this Punnett square, we see that there are two possible genotypes for the offspring: EE and Ee. From this, we can conclude that the mother's genotype is indeed Ee, as she can pass on either the dominant E or the recessive e allele to her offspring.

So, to summarize, in the Punnett square, the mother would be represented as Ee, indicating that she is heterozygous with a dominant allele (E) and a recessive allele (e) for the number of eyes.
