STUDY GUIDE BIO 311D CHINNERY SPRING 2007 CHAPTER 13 (lectures 1, 2, 3) Pgs 238-250 Important figures: 13.2, 13.4, 13.5, 13.6, 13.7, 13.8, 13.9, 13.10, 13.11 Important terms: heredity, variation, genetics, gene, locus, asexual reproduction, clone, sexual reproduction, meiosis, diploid, haploid, somatic cell, gamete, chromosome, homologous chromosome, sex chromosome, autosome, fertilization, chromatid, zygote, interphase, prophase, metaphase, anaphase, telophase, cytokinesis, tetrad, independent assortment. Learning objectives : Define sexual and asexual reproduction and give examples. Explain how sexual and asexual reproduction differ with respect to the genetic identity of parent(s) and offspring. Draw the three general life cycles of plants, animals and fungi. Identify all structures and processes in each life cycle. Define mitosis, meiosis, fertilization. Explain how fertilization and meiosis relate to the formation of haploid and diploid cells.

Unformatted text preview: Identify which cell can undergo mitosis to produce a multicellular organism, and explain how the life cycles of plants, animals and fungi differ in this regard. Explain how you can generate four haploid cells from one diploid cell. Define homologous chromosome, sister chromatid, maternal and paternal chromosomes, tetrad. Draw and explain how chromosomes are sorted during meiosis. Identify the stage when homologous chromosomes are separated. Identify the stage when sister chromatids are separated. Explain at what stage in meiosis (a) recombination (crossing over) and (b) independent assortment occur. Explain the adaptive value of recombination. What does it mean to say that (non-homologous) chromosomes undergo independent assortment? Explain how many different combinations of haploid chromosomes can be produced by meiosis of a diploid cell with N chromosomes....
