mary is a green-eyed mother who is married to brown-eyed Jackson, and they have four children. Brown is the dominant allele, and green is the recessive allele. Three of their four children have brown eyes, and one has green eyes. How can you explain this?
If you draw a punnet square with the recessive and dominant allele's you'll see that there is a 25% chance even when both parents have brown eyes. Have a nice day! :)
