Figure 7.2 (a) In animals, sexually reproducing adults form haploid gametes from diploid germ cells. (b) Fungi, such as black bread mold (Rhizopus nigricans), have haploid-dominant life cycles. (c) Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism.

A diploid cellculture was established and, at premitotic S phase, aradioactive nucleotide was added and was incorporatedinto newly synthesized DNA. The cells were then removed from the radioactivity, washed, and allowed to proceed through mitosis. Radioactive chromosomes or chromatids can be detected by placing photographic emulsionon the cells; radioactive chromosomes or chromatids appeared covered with spots of silver from the emulsion.(The chromosomes “take their own photograph.”) Drawthe chromosomes at prophase and telophase of the firstand second mitotic divisions after the radioactive treatment.
