MEIOSIS makes gametes

MEIOSIS makes gametes. Meiosis produces gametes. Meiosis was first observed by the Belgian cytologist Pierre-Joseph van Beneden in 1887 60 years before we knew that DNA contained the genetic material Gametes (eggs and sperm) contain half the complement of chromosomes found in other cells

Evolution

Evolution. Genetic Variation. When we picture penguins we imagine them all the same. Perfect little carbon copies, genetic clones of black and white, wobbly, birdlike creatures that like ice. They vary greatly, however, when you take a closer look. Genetic Variation.
