Document Summary
Notes when laptop wasn"t working: not homologous and can"t cross over (cid:523)don"t know which one) but they only, huge difference in number of chromosomes in different organisms. Sex chromosomes in humans use tops to cross over. Sex chromosomes in grasshoppers: females get x from mother and x from father, males get x from mother and the other cell receives nothing xx will become female and xo will get nothing. Why are morgan"s experiments so important: don"t need to memorize the picture like you would anyways ;p. Nondisjunction as proof of the chromosome cause a pair of homologues into one cell when other cell receives nothing: white eye coming again demonstrated c chromosome carried white eye male. Assortment: shows independent assortment, chromosomes in metaphase i can line up either way as sown in the two pictures and this gives the law of independent assortment to give off random combinations of assortment.
