1 Reproduction & genetics Donald Winslow 16 September 2010 Readings from Hoefnagels 2009. Biology, McGraw-Hill, New York. Ch. 8 pp 154-163 (cell cycle & mitosis) Ch. 9 pp 174-182 (meiosis & sex) Ch. 10 pp 196-203 (Mendelian genetics)

2 Reproduction Cellular reproduction  Somatic Genome, genes in DNA in nucleus Cell cycle  G 1, S, G 2, Mitosis  Gametic Meiosis Organismal reproduction

3 The cell cycle G1G1 S G2G2 M

4 Organismal reproduction Types of reproduction  Asexual  Sexual Life cycles Genetics Costs of sexual reproduction Advantages of sexual recombination

5 Types of reproduction Asexual  cloning binary fission budding  Ameiotic & meiotic parthenogenesis sexual  dioecy (separate sexes)‏  monoecy (hermaphroditism)‏

6 Figure 7.1 From Hickman et al. 2006 (13 th ed.)‏

7 Generalized sexual lifecycle femalemale Ovum sperm (gametes, 1N) meiosis 2N fertilization zygote (2N)‏ embryo development

8 Genetics Gregor Mendel Alleles, genes, and genomes Genotype & phenotype Dominance relations among alleles Monohybrid & dihybrid crosses Segregation & independent assortment Human blood groups
