This post would be about something else had you payed attention in 8th grade.

You know the deal. You're defending prenatal rights online. Perhaps even more certain than Godwin's Law, a Roebot will eventually submit some form of this argument. Examples below.

  • If abortion is murder, masturbation is genocide. (and/or some reference to the "Tubesock Holocaust")
  • If abortion is murder, any woman who's ad more than one period is a serial killer!

Now, for this post I'm going to assume a fundamental understanding of the subject of biolo-...
Actually, I'd better not.

You see, sperm and egg cells (reproductive cells that fuse to form a zygote, collectively referred to as gametes) are formed through a process called meiosis, in which-

Whoa, there! Don't you think I should handle this?

Um, this is kind of my blog. Who are you exactly?

I'm Gamete Pete!

Err... okay?

Anyway, meiosis occurs when a body cell splits in two, copying its chromosomes as in mitosis, resulting in 2 daughter cells with a normal number of chromosomes. Next each of these daughter cells splits in two, but do not copy their chromosomes. The result is that the original parent cell produces four new cells with half a full set of chromosomes. This occurs in both the male and the female, though in the female 3 of the 4 granddaughter cells merely become polar bodies. This is simplified, but it's enough for our purposes. When half the chromosomes from a mother and half the chromosomes from the father join in a process called fertilization, a new organi-

I'm Kate the Prenate!

I should've expected.

When the father's spermatozoon (sperm) fertilizes the mother's ovum (egg cell), the two half-genomes (sets of chromosomes) join to form a new genome, thus a new and unique organism is formed. Unlike gametes, which are cells of the parent, the zygote (the single celled organism created by the union of the two gametes) is a new organism. The zygote then begins to grow through mitosis into a blastocyst. In viviparous animals, the blastocyst travels down a fallopian tube of the mother into her uterus, implants in the uterine lining, and becomes an embryo. In humans, the stage of development after approximately five months is termed the fetal stage, and the individual is termed a fetu-


No, sorry Cletus. No.

As you can see, there is no comparison to be made. Gametes are cells of the parent and a prenate is a separate individual. A gamete has the potential to contribute half of the genome of a human being. A prenate is a human being.
