Genetic puzzle

3. A mature haploid male or female germ cell (sperm or egg).
5. A diploid cell resulting from the fusion of two haploid gametes.
7. A cell containing only a single set of chromosomes (n), such as a sperm or egg.
10. First stage of mitosis; chromatin condenses and the nuclear envelope breaks down.
11. Phase of mitosis where sister chromatids are pulled apart to opposite poles.
12. One of two identical "sister" halves of a replicated chromosome.
13. A structure of nucleic acids and protein carrying genetic information.
14. REPRODUCTION Process involving two parents that combine genetic material to produce a unique organism.
16. REPRODUCTION Mode of reproduction involving a single parent; results in offspring identical to the parent.
17. Type of cell division resulting in two daughter cells each identical to the parent.
20. OVER Process where homologous chromosomes exchange portions of their chromatids.
21. Term for chromosomes that have a corresponding chromosome from the opposite parent.

1. Phase of mitosis where chromosomes line up in the middle of the cell.
2. The region where two sister chromatids are joined together.
4. Final stage of mitosis; two new nuclear envelopes begin to form.
6. The final division of the cytoplasm to form two separate daughter cells.
8. A cell containing two complete sets of chromosomes (2n).
9. A structure containing four chromatids that forms during meiosis.
12. CYCLE The series of events that take place in a cell leading to its division and duplication.
15. The longest phase of the cell cycle where the cell grows and replicates DNA.
18. SPINDLE Microtubule structure that helps separate chromosomes during mitosis.
19. Process of cell division that produces reproductive cells with half the chromosomes.
