Genetics
Across
- 2. A segment of DNA on a chromosome that codes for a specific trait
- 4. organism's genetic makeup or allele combination
- 5. cell division that produces reproductive cells in sexually reproducing organisms
- 7. region where two sister chromatids are joined tightly together
- 9. an organism that has two different alleles for a trait
- 12. A complex molecule containing the genetic information that makes up the chromosomes
- 14. A characteristic that an organism can pass on to its offspring through its genes
- 15. A gene that has more than two alleles
- 16. chart that shows all the possible combinations of alleles that can result from a genetic cross
Down
- 1. physical traits you can see
- 3. The passing of traits from parents to offspring
- 6. having two identical alleles for a trait
- 8. one of two identical strands into which a chromosome splits during mitosis
- 10. is hidden whenever the dominant allele is present
- 11. an allele whose trait always shows up in the organism when the allele is present
- 13. cell division in which the nucleus divides into nuclei containing the same number of chromosomes
