A member asked:
What are dominant vs recessive gene diseases?
A doctor has provided 1 answer
See below: With a dominant gene trait, the child only needs to receive one copy of the abnormal gene. So, they have a 50% chance of getting the gene. With a recessive gene, the child needs 2 copies of the gene. So, they have a 25% chance of having both genes.
