11.4 Meiosis – We studied gene linkage and gene maps. We completed data analysis on gene location and crossing-over. We used the probability of phenotypes to construct a gene map. We learned that a tetrad means four chromatids formed by two pairs of replicating chromosomes. A zygote is a cell produced by the union of egg and sperm. We discovered the difference between mitosis and meiosis. Mitosis produces two diploid cells such as in body cells. Meiosis produces gametes or four haploid cells. Tetrads are formed and crossing-over occurs.
