1. Fill in this table: Mitosis Meiosis Type of reproduction (sexual or asexual) Fof cell'nuclear divisions Synapse/ crossing over? (yes or no) Centromeres dissolve during anaphase? Meiosis I? Meiosis II7 Chromosome # at beginning? Chromosome # at end of process? Meiosis I? Meiosis II? F of daughter nuclei? Daughter cells the same as parent cell? Daughter cells genetically identical to cach other?

Which statement best describes the genetic content of the two daughter cells in prophase II of meiosis? haploid with one copy of each gene haploid with two copies of each gene diploid with two copies of each gene diploid with four copies of each gene

Tetraploidy may result from: a. lack of cytokinesis in meiosis II b. nondisjunction in meiosis I c. lack of cytokinesis in mitosis d. nondisjunction in mitosis in the early embryo e. none of these

The chromosome constitution number of this individual is 2=6. This drawing represents: a. mitotic metaphase. b. meiotic metaphase I. c. meiotic metaphase II. d. a gamete. e. sixnonhomologous chromosomes.

Match the description with the phase of meiosis. Letters may be used more than once. Homologous chromosomes line up at the equator. 1. prophase I The nuclear membrane 2. metaphase I dissolves around a haploid number of chromosomes. 3. anaphase I Disjunction (separation) of homologous chromosomes 4. telophase I occurs. 5. prophase II Centromeres divide and sister chromatids separate. 6. metaphase | Crossing-over begins. 7. anaphase II 8. telophase II Synapsis occurs. > >

9. Complete the chart below comparing the process of mitosis to meiosis.   mitosis meiosis Purpose       #cell divisions (1 or 2)       #cells produced (2 or 4)       Are new cells gametes or somatic cells?     Are new cells haploid or diploid?       Does crossing over occur? When?       Are new cells genetically identical or Different than parent cell?
