Everyone has two sets of genes: one from Mom and one from Dad. When a sperm (carrying Dad’s DNA) fertilizes an egg (containing Mom’s DNA), those two sets of DNA (which include chromosomes and genes) combine to make a new mixture — the unique genome of their baby. A genetic disease is when a gene from one or both parents contains a mutation (a chang...
