Explanation:the ovum is first released(ovulation) then a sperm merges with it (fertilization) the zygote is moved to the uterus(implantation) it grows to become a baby and the mother delivers it(birth)

Ovulation > fertilization > implantation > birth

I'm not sure how detailed this needs to be but I'll try. DNA is a self-replicating material and the carrier of genetic information. 99% of DNA between to people will be identical but it's the 1% that makes us unique (honestly it's more like 99.9% and 0.01% but I wasn't sure if that's completely right). The more closely two people are related, the more similar their DNA will be. That's why DNA has been used as a powerful tool in court cases. DNA can be found at a crime scene and then be used to identify a culprit, victim, witness, or accomplice. Forensic scientists are able to take small biological samples and analyze them to create a DNA profile. Usually the best evidence occurs when a person's DNA is found where it isn't supposed to be. They can find DNA on objects such as: bottles, weapons/tools, hairbrushes, condoms, dirty laundry, etc. I'm not sure if this is what you were looking for but I hope it helps!
