Unformatted text preview: 1 2 The four chromatids in each cluster during synapsis; formed by the two sister chromatids in each of the two homologous chromosomes. 1 3 Cell division in which the chromosomes replicate, followed by two nuclear divisions. Each of the resulting gametes (in animals, spores in plants) receives a haploid set of chromosomes. 1 4 The chromosomal characteristics of a cell; also, a representation of the chromosomes aligned in pairs. in preparation for the next division; consists of gap 1 (G1), synthesis (S), and gap 2 (G2). 5 Division of cells to replace worn out, damage or to growth cells, and to produce gametes. 6 Cells that contain homologous chromosomes. The number of chromosomes in the cells is the diploid number and is equal to 2n . 8 Haploid reproductive cells (ovum and sperm). 9 Is unrestrained cell growth and division 1 1 A diploid cell resulting from fertilization of an egg by a sperm cell. 2...
