Gametes have a haploid number (23). When conception occurs, a human sperm and ovum combine their chromosomes to make a zygote (fertilized egg) with 46 chromosomes. This is the same number that the parents each had in their somatic cells. In doing this, nature is acting conservatively. Each generation inherits the same number of chromosomes.
In order for the egg to be fertilized, there needs to be sperm present, or intercourse needs to be done within the first 12 hours of ovulation. With these circumstances in mind, itâs important to know when ovulation does occur through fertility charting. I believe that conception happens the minute the sperm and egg combine. This happens within 24 hours after ovulation occurs. The body will not know itâs pregnant until the fertilized egg implants into the uterine wall, some 5 to 12 days after ovulation.
