1. | Locus | A. | a chromosome that is similar in appearance and genetic information to another chromosome with formation with which it pairs during meiosis |
2. | Gamete | B. | the first stage of mitosis, in which the chromosomes first become visible in the light microscope as thickened, condensed threads and the spindle begins to form; as the spindle is completed, the nuclear envelope splits apart, and the spindle fibers invade the nuclear region and attach to the kinetochores of the chromosomes |
3. | Haploid | C. | a form of reproduction in which genetic material from two parent organisms is combined in the offspring: normally, two haploids gametes fuse to form a diploid zygote |
4. | Meiosis | D. | the stage of the cell cycle between cell divisions; the stage in which chromosomes are replicated and other cell functions occur, such as growth, movement, and acquisition of nutrients |
5. | Mitosis | E. | meiosis followed by cytokinesis |
6. | Prophase | F. | microtubules organized in a spindle shape that separate chromosomes during mitosis or meiosis |
7. | Telomere | G. | a preparation showing the number, sizes, and shapes of all chromosomes within a cell and, therefore, within the individual or species from which the cell was obtained |
8. | Homologue | H. | a protein structure that forms at the centromere regions of chromosomes; attaches the chromosomes to the spindle |
9. | Karyotype | I. | the formation of new combinations of the different alleles of each gene on a chromosome: the result of crossing over |
10. | Metaphase | J. | a eukaryotic chromosome following DNA replication; consists of two sister chromatids joined at the centromeres |
11. | Telophase | K. | a nuclear division in which one copy of each chromosome (already duplicated during interphase before mitosis) moves into each of two daughter nuclei; the daughter nuclei are therefore genetically identical to each other |
12. | Interphase | L. | the physical location of a gene on a chromosome |
13. | Kinetochore | M. | a type of nuclear division in which a diploid nucleus divides twice to form four haploid nuclei |
14. | Recombination | N. | mitosis followed by cytokinesis |
15. | Sex Chromosome | O. | the stage of mitosis in which the chromosomes, attached to spindle fibers at kinetochores, are lined up along the equator of the cell |
16. | Sexual Reproduction | P. | a haploid sex cell formed in sexually reproducing organisms |
17. | Spindle Microtubules | Q. | referring to a cell that has only one member of each pair of homologous chromosomes |
18. | Duplicated Chromosome | R. | the nucleotides at the end of a chromosome that protect the chromosomes from damage during condensation, and prevent the end of one chromosome from attaching to the end of another chromosome |
19. | Meiotic Cell Division | S. | the final stage, in which the spindle fibers usually disappear, nuclear envelopes re-form, and cytokinesis generally occurs. In mitosis and meiosis Ⅱ, the chromosomes also relax from their condensed form |
20. | Mitosis Cell Division | T. | the pair of chromosomes that usually determines the sex of an organisms; for example, the X and Y chromosomes in mammals |
