Is the scientific study of heredity and hereditary variation: genes. The complete complement of an organism"s genes: traits are coded in dna, each gene in an organism"s dna. Has a specific locus on a certain chromosome: we inherit . One set of chromosomes from out mother and one set from out father: gametes. Reproductive cells - vehicles of genes: ex: sperm, oocyte. Deliver father and mother genetic info to form the next generation organism. Only have half of genetic info (chromosomes) To prepare arrest the cell in metaphase b/c that is where the chromosomes are most condensed and give the best picture quality: human karyotypes: what is the difference in chromosomes between these two karyotypes https://onedrive. live. com/view. aspx?resid=c5310d6a66e98d52!121&app=onenote&authkey=!apqq1udavatjxly. Determine mutations: prevent microtubules from pulling sister chromatids apart by putting drops that inhibit that disassembling of chromatids. Are the 2 chromosomes composing a pair.
