Unattached earlobes is a dominant trait, E. A parent who is homozygous for unattached earlobes is crossed with a parent who is homozygous for attached earlobes. Which describes the genotypes of their offspring?

Homozygous Dom and Homozygous recessive traits are both shown.

Look below for answer V

Explanation:

Considering that both are homozygous, that means that both traits are of the same kind.

Unattched earlobes is dominant, which means its sign would be (EE)

Attatched is the recessive, which means its sign would be (ee)

On a table, the genes would look this way-

         EE             EE

ee     Ee              Ee

ee     Ee              Ee

Since there is a dominant trait in all of the genes, the children would 100% have unattached earlobes.

(As a counter situation, if the unattatched was heterozygous, the chance of attatched to unattatched would be 50/50 as theres no dominant trait lurking)

I may be incorrect but i hope this helps!
