Chapter 8 Difference between binary fission of a bacterium and human cell division: 1. a bacterium has only one chromosome 2. human cells undergo mitosis and cytokinesis 3. bacteria are smaller and simpler than human cells 4. human chromosomes are larger and more complex True about human somatic cells: 1. they arise by mitotic cell division 2. they are body cells other than eggs and sperm 3. they are larger and more complex than bacterial cells 4. they contain 46 chromosomes sister chromatids: are produced during S prophase II of meiosis functions of mitotic cell division in animals: 1. asexual reproduction 2. growth 3. repair of damaged organs 4. cell replacement meiosis: halves the number of chromosomes in cells. Crossing over is: important in genetic recombination Human somatic cells are diploid, and human gametes are haploid Followings leading to genetic variability: 1. random fertilization 2. crossing over during meiosis 3. orientation of chromosomes during metaphase I of meiosis 4. mutation
