A segment of DNA from one chromatid in the tetrad goes to another chromatid in the tetrad. The result is a genetically new chromatid - which means that all four chromatids in the tetrad are genetically different than before.

C Diploid chromosomes with the same length and shape whose genes deal with the same traits (like eye color) that line up in meiosis. A pair of sister chromatids.
