Remember, that these answers are one possibility. Check with your teacher if you think you may have an answer that is correct
Answers • Heterozygous parent: Dd; homozygous recessive parent: dd; Two squares would be Dd, and two would be dd. Therefore, there would be a 50% chance of Dd, and a 50% chance of dd. • Homozygous dominant parent: DD; homozygous recessive parent: dd; their children would all be Dd • Two heterozygous parents would both be Dd; their children – one square would have DD, one dd, and two Dd. Therefore, they would have a 25% chance of DD, a homozygous dominant child, 25% chance of dd, a homozygous recessive child, and a 50% chance of Dd, a heterzygous child.
