In humans, the straight cut of the eyes dominates over the oblique. What kind of eye shape

In humans, the straight cut of the eyes dominates over the oblique. What kind of eye shape can you expect in children whose parents are heterozygous for this trait?

Let’s designate the gene that causes the straight cut of the eyes in humans as D, then the gene that leads to the development of the oblique cut of the eyes will be designated as d.

Dd’s heterozygous parents will have straight eyes and will produce two types of eggs and sperm, d and D.

The possible offspring of a given married couple may include the following options:

children with straight eyes (DD and Dd) – 75% of the offspring;

children with slanting eyes (dd) – 25% of offspring.
