Across
- 3. division of the cytoplasm
- 6. period of the cell cycle between cell
- 10. type of reproduction in which cells from two parents unite to form the first cell of a new organism
- 11. Process in sexual reproduction in which male and female reproductive cells join to form a new cell
- 14. series of events that cells go through as they grow and divide
- 17. likelihood that a particular event will occur
- 18. Passing of traits from parents to offspring
- 20. Different forms of a gene
- 21. threadlike structures made of DNA molecules that contain the genes
- 22. Situation in which one allele is not completely dominant over another allele
- 24. DNA segments that serve as the key functional units in hereditary transmission.
Down
- 1. Chromosomes that have the same sequence of genes and the same structure
- 2. Describes a trait that covers over, or dominates, another form of that trait.
- 4. A reproductive process that involves only one parent and produces offspring that are identical to the parent.
- 5. An organism's physical
- 7. A chart that shows all the possible combinations of alleles that can result from a genetic cross
- 8. A comparison of two quantities by division
- 9. A diagram that shows the occurrence of a genetic trait in several generations of a family.
- 12. genetic makeup of an organism
- 13. Cell division that produces reproductive cells in sexually reproducing organisms
- 15. A condition in which neither of two alleles of a gene is dominant or recessive.
- 16. part of eukaryotic cell division during which the cell nucleus divides
- 19. An allele that is masked when a dominant allele is present
- 23. A complex molecule containing the genetic information that makes up the chromosomes
