BIO NOTES – Meiosis --1 st slide: diploid; every gene has a partner --alleles = genes that occur at the same loci on homologous chromosomes --ovaries/testes = gonads, sperm/eggs = gametes (animals); anther & ovary (plants) A. Meiosis I a. individual chromosomes (homologues) pairs w/ its partner b. Prophase I = every homologue finds its partner (tetrad formation) c. Telophase I = chromosomes arrive at opposite poles; usually followed by cytoplasmic division d. cell is haploid at the end B. Meiosis II a. 2 sister chromatids of each duplicated chromosome are

Unformatted text preview: separated from each other b. Prophase II = spindle forms c. Metaphase II = chromosomes to spindle equator d. Anaphase II = sister chromatids separate independent chromosomes e. Telophase II = chromosomes at opposite ends; nuclear envelope forms; total of 4 haploid cells--23 chromosomes in one of our gametes (1n); 46 = 2n--at the end of meiosis I, each cell will be haploid (separated sister chromatids)--gametes, some plant parts are haploid cells...
