Chapter 9: Cellular Basis for Inheritance
Name:__________________
1. asexual reproduction- process in which a single cell or set of cells produces offspring
that inherit all their genetic material from one parent
2. sexual reproduction- process in which genetic material from two parents combines
and produces offspring that differ genetically from either parent
3. chromatin-DNA and protein molecules in long, thin fibers; genetic material of the
eukaryotic nucleus
4. chromosome- condensed threads of genetic material formed from chromatin as a cell
prepares to divide
5. sister chromatid- one of a pair of identical chromosomes created before a cell divides
6. centromere- region where two sister chromatids are joined together
7. cell cycle- sequence of events from the production of a eukaryotic cell to the time the
cell itself reproduces
8. interphase- stage of the cell cycle during which a cell carries out its metabolic
processes and performs its functions in the body
9. mitotic phase- stage of the cell cycle when a cell is actively dividing
10. mitosis- a nucleus and duplicate chromosomes of a cell divide and are evenly
distributed, forming two daughter nuclei
11. cytokinesis- process by which the cytoplasm of a cell is divided into two; usually
follows mitosis or meiosis
12. prophase- first stage of mitosis and of meiosis I and II, when the already replicated
chromosomes condense
13. metaphase- second stage of mitosis and of meiosis I and II when the spindle is fully
formed and all of the chromosomes are held in place
14. anaphase- third phase of mitosis and of meiosis I and II, in which the sister
chromatids separate and move toward the poles of the spindle
15. telophase- final stage of mitosis and of meiosis I and II, in which the chromosomes
reach the spindle poles, nuclear envelopes form around each set of daughter
chromosomes, and the nucleoli reappear
16. benign tumor- mass of cells that remain at their original site
17. malignant tumor-mass of abnormal cells resulting from uncontrolled canceer cell
division
18. cancer- disease caused by severe disruption of the mechanisms that normally control
the cell cycle
19. metastasis- spread of cancer cells beyond their original site in the body
20. meiosis- type of cell division that produces 4 cells, each with half as many
chromosomes as the parent cell
21. karyotype- display of a person's 46 chromosomes
22. homologous chromosome- one of a matching pair of chromosomes, one inherited
from each parent
23. sex chromosome- one of the two chromosomes of the 23rd pair of human
chromosomes which determine an individual’s gender
24. diploid- having two homologous sets of chromosomes
25. gamete- egg or sperm sex cell that contains a single of chromosomes, one from each
homologous pair
26. haploid- having a single set of chromosomes
27. fertilization- the fusion of the nucleus of a haploid sperm cell and the nucleus of a
haploid egg cell, forming a diploid zygote
28. zygote- diploid cell formed when the nucleus of a haploid sperm cell fuses with the
nucleus of a haploid egg cell
29. crossing over- exchange of genetic material between homologous chromosomes
during prophase I of meiosis
30. genetic recombination- new combination of genetic information in a gamete as a
result of crossing over during prophase I of meiosis
31. spindle- framework of microtubules that guide the movement of chromosomes
during mitosis and meiosis
