Meiosis and Cell Cycle

chromosome that contains genes for characteristics not related to the sex of an organism

                             example: in humans pairs #1-22

• Autosome

• sex chromosome

• haploid

• diploid

asexual reproduction where 1 cell divides into 2

• splitting

• Binary Fission

• dividing

• haploid

series of events that take place in a cell leading to its division and duplication.  Has 3 main phases:

interphase, nuclear division, and cytokinesis

• mitosis

• Cell Cycle

• meiosis

region of condensed chromosome where spindle fibers attach during mitosis and meiosis

• chromatid

• centriole

• chromosome

• Centromere

single piece of coiled DNA, contains genes that code for traits

• Centromere

• Centriole

• Chromosome

• Chromatid

one half of duplicated chromosome, joined at the centromere

• Centriole

• Chromatid

• Chromosome

• Centromere

an exchange of genetic material between homologous chromosomes during anaphase 1 of

meiosis, causes genetic variability

• Crossing Over

• nondisjunction

• mutation

final phase of cell cycle, where the cytoplasm divides

• cytoplasm

• Cytokinesis

• interphase

cell with 2 copies of each chromosome, one from the egg and one from the sperm (represented by 2n)                         

              example: in human body cells 2n = 46

• Diploid

• Haplid

• Hapling

• Dipling

specialized cell (egg or sperm) used in sexual reproduction, has ½ the normal number of  

chromosomes of a somatic cell

• Gamete

• somatic cell

• body cell
