During the first 24 hours of pregnancy, a sperm fertilizes an egg, combining DNA from both parents to create a unique genetic blueprint. This forms a single cell called a zygote, which contains all instructions needed to build a baby. The fertilized egg immediately begins preparing for its first cell divisions and starts its journey through the fallopian tube toward the uterus.
