In humans, non-red hair (A) dominates over red hair (a). Father and mother are heterozygous non-redheads. They have eight children, all redheads. Determine the genotypes of all the specified family members according to the “red / non-red” character.

Since the parents are heterozygous, they carry one gene for red hair. Theoretically, they can have 2 red children (25%). But the meeting of gametes during fertilization occurs by chance and therefore all all red children, as well as any combination of red / non-red ones, can be born in a given family.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
