In humans, the ability to better control the right hand dominates over left-handedness, and brown eye color

In humans, the ability to better control the right hand dominates over left-handedness, and brown eye color over blue. A diheterozygous right-handed brown-eyed young man married a heterozygous right-handed blue-eyed girl. What genotype and phenotype can be children in this family?

Let’s designate the gene for right-handedness as G, the gene for left-handedness as g. Let’s designate the gene for brown eye color as C, blue as c.

Diheterozygous youth – GgCc. The spermatozoa it produces are gc, GC, Gc, gC.

Heterozygous right-hander with blue eyes – Ggcc. The eggs it produces are Gc, gc.

The probable offspring of this family will be represented by the following options:

right-handed children with blue eyes (2Ggcc, GG cc);

right-handed children with brown eyes (GGCc, 2 GgCc);

left-handed children with blue eyes (ggcc);

left-handed children with brown eyes (ggCc).
