Across
- 2. A long strand of DNA that contains genes.
- 5. Genetic material found on chromosomes that provide instructions of all traits and cellular activities.
- 8. The process by which organisms with beneficial traits survive and reproduce at a higher rate than organisms without these traits.
- 11. The passing of traits from parent to offspring.
- 12. A segment of DNA, made of alleles, whose code determines traits.
- 13. A plants response to external stimulus.(photo=light, geo=gravity, hydro=water).
- 14. Reproduction in which a single parent produces offspring thus they are genetically identical to the parent.
- 15. Characteristics that is learned or developed over time dure to envirinmental factors, it is not inherited from parents.
Down
- 1. Specific variations in the characteristics of organisms passed from a parent or ancestor to offspring during reproduction.
- 3. Reproduction that requires two parents where each parent passes an allele on to the offspring resulting in genetic variation.
- 4. Different forms of a characteristic (brown or blue eyes) receoved from parent/s. Traits can be recessive or dominant.
- 6. Process by which the traits (internal or external) of a population change over time to better fit the enviorment which the population lives in.
- 7. Different versions of a gene, one part of a gene that determines a specific trait.
- 9. Organelle in eukaryotic cell that contains genetic informaation(DNA).
- 10. Study of genes, heredity, and variation of living organisms.
