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!

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
