In humans, the presence of freckles dominates over their absence. Will children have freckles

In humans, the presence of freckles dominates over their absence. Will children have freckles if their parents are heterozygous for this trait?

Let the gene that causes the presence of freckles be W, and the gene that leads to their absence – w.

Parents, according to the condition of the problem, are heterozygotes – Ww. They have freckles. The eggs and spermatozoa they produce are W and w.

The offspring of such people will be represented by the following options:

freckled children – homozygotes (WW) – 25%;

homozygous children without freckles (ww) – 25%;

freckled children – heterozygotes (Ww) – 50%.

Answer: 75% of children born to heterozygous parents will have freckles.
