Document Summary
Jan 21 biol 2040: what is the ploidy of the cell above triploid (count centromere!, there is only 2 different chromosomes (by size) Tells where the chromosome is, and even some telomere: g banding (only x chromosome have that banding), (q and p arms) Reflects heterogeneity of chromosomes (based on certain sequence) it is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is useful for identifying genetic diseases through the photographic representation of the entire chromosome complement. orientate who we are , Ploidy (how many unique chromosome we have!!: ploidy refers to the number of complete sets of chromosomes, set = all unique/diff chromosomes. A colleague shows you the following karyotypes for two new recently discovered organisms. Even if they look the same, they may have different number of chromosome. You can not tell how they look like or what feature they have, complexity of organism: organization of dna.
