And this separation process that takes place when we actually form the gametes is known as law of segregation. So this idea that the two hereditary factors our genes for any given trait, in this case, our heights segregate from one another during gammy formation became known as Mendel's law of segregation. Now, the amazing thing about this discovery was this was basically discovered at the time when we knew nothing about meiosis or Mitosis. So even though at the time when mendel made the discovery, we knew what gametes were and we knew that gametes must fertilize to form the Zygote. We knew nothing about how Meiosis takes place and so we knew nothing about how the gametes are actually formed. So although this was actually correct, it wasn't exactly correct.
