6. Chart that shows all the possible combinations of alleles that can result from a genetic cross.
8. In the next part of interphase, the cell makes an exact copy of the DNA in its nucleus in a process.
10. The final stage of the cell cycle.- completes the process of cell division.
12. The passing of physical characteristics from parents to offspring.
15. One whose trait always shows up in the organism when the allele is present.
17. A purebred organism is the offspring of many generations that have the same trait.
18. A new organism begins to form when egg and sperm join in the process.
19. The stage during which the cell’s nucleus divides into two new nuclei.
20. The first stage of the cell cycle
22. A number that describes how likely it is that an event will occur.
23. The scientific study of heredity.

1. The different forms of a gene.
2. Each different form of a characteristic, such as stem height or seed color.
3. An organism that has two identical alleles for a trait.
4. Hidden whenever the dominant allele is present.
5. Genetic makeup, or allele combinations.
7. During prophase, the threadlike chromatin in the nucleus condenses to form double-rod structures.
9. cycle The regular sequence of growth and division that cells undergo.
11. An organism that has two different alleles for a trait.
13. A hybrid organism has two different alleles for a trait.
14. An inheritance pattern.
16. The factors that control a trait.
21. Physical appearance, or visible traits.
