BIOL 302 Chapter Notes - Chapter 9: Red Queen Hypothesis, Asexual Reproduction, Hermaphrodite
Document Summary
Chapter 9 reproductive strategies: (shout out to my biol 369 peeps and dr. chip ) Sexual selections favour traits that facilitate reproduction. Sexual reproduction: a reproduction mechanism in which progeny inherit dna from two parents. Production of haploid cells contains a single full set of chromosomes: mixing of haploid cells (chromosomes) are random. Two gametes join in act of fertilization to produce a diploid zygote. Asexual reproduction: a reproduction mechanism in which progeny inherit dna from a single parent. Vegetative reproduction: a form of asexual reproduction in which an individual is produced from the nonsexual tissues of a parent. Example: many plants: clones: individuals that descend asexually from the same parent and bear the same genotype. Binary fission: reproduction through duplication of genes followed by division of the cell into two identical cells. Example: bacteria duplication of a gene followed by a division of the cell into two identical ones.
