Instead of stupid comments, why don't you write what you think happens at conception when it comes to DNA including your X and Y chromosomes. It happens at conception. It happens when the Gametes come together in the fertilization process and combine to form a single complete genome. This fusion to form the Zygote creates a single cell with all the DNA components to divide and replicate. Some want to nitpick and say it's not a creation of a new person but an inheritance of family traits. Whatever. It's a new separate individual with it's own set of DNA including the X and Y chromosomes that decide male or female.
On a similar note, the new personage being developed is a living Zygote and continues to grow throughout it's entire life. Well, we do start to break down after 30 or so years. That Zygote is not part of the mother but a completely new personage. It's life is supported by the mother. And, that's where the debate on abortion comes in. Because it is now a separate personage growing (alive) in the mother's womb, does it have the right to continue to live and grow through it's birth outside the mother? Abortionists say it's tissue part of the mother and therefore, she has the right to get rid of foreign tissue. Anti-abortionists say because the zygote has it's own DNA and is an individual personage at conception, it should have the right to live through birth and beyond. Because the Zygote-Embryo-Fetus cannot defend it's own right to live and grow, adults like Charlie Kirk are defending that child's rights as a separate living personage. And, it's the mother's responsibility to give it nourishment throughout the gestation period and beyond until the child can fend for itself. Which is in our laws, 18 years of age. Until then, the mother has the responsibility to raise the child. If she cannot, then put the child up for adoption, not kill it whether it's in one of the three prebirth trimesters or from age 0 to 18.
