Solve situational problems and answer the questions:
In humans, the gene is dominant over brown eyes blue eyes, and the ability to use mostly the right hand - over the left-handers. Both pairs of genes located on different chromosomes. What could be the children if the father is left-handed, but heterozygous for eye color, and the blue-eyed mother, but heterozygous for the ability to own hands.
