Chapter 2
Reproduction and Chromosome Transmission
Study Outline
1. General features of chromosomes
1. Eukaryotic chromosomes are examined cytologically to yield a karyotype
2. Eukaryotic chromosomes are inherited in setss
2. Cell division
1. Bacteria reproduce asexually by binary fission
2. Eukaryotic cells progress through a cell cycle to produce genetically identical daughter
cells.
3. Traits are governed by genes and by the environment
3. Mitosis and cytokinesis
1. The mitotic spindle apparatus organizes and sorts eukaryotic chromosomes
2. The transmission of chromosomes during the division of eukaryotic cells involves a
process known as mitosis
4. Meiosis
1. Meiosis produces cells that are haploid
5. Sexual reproduction
1. In animals, spermatogenesis produce four haploid sperm cells and oogenesis produces a
single haploid egg cell
2. Plant species alternate between haploid (gametophyte) and diploid (sporophyte)
generations
