1/22/09 CH. 3 (talked about genetic variability) homologous chromosomes- two unhatched lines in picture and two hatched lines  in picture; 23 pairs of homologous chromosomes in our cells; they have the same  sequence of genes; genes located in same exact position on each one;  (pic: now they replicate and have 8—2 chromatins held together by centromere; chromatin- DNA strands that are identical centromere- part of the chromosome that holds 2 chromatids together Mitosis: Interphase- genes are active; chromosomes replicate Prophase-  Metophase- chromosomes align independently from one another Anaphase- centromeres divide Telophase-  (pictures that go along with these phases) Results of mitosis: - 2 cells are formed and both cells have the diploid chromosome number Diploid- full complement of chromosomes (46) - both daughter cells are genetically identical with the parent cell and each
