Across
- 5. the range of expression of a trait within a population
- 8. the study of genes and how they affect the traits of an organism
- 9. the passing on of genetic traits from parents to offspring
- 11. the traits produced by the genotype; the expression of genes
- 12. an organism's complete set of DNA
- 14. a form of a gene that is expressed only when a dominant allele is not present
Down
- 1. a structure made of coiled DNA that transfers hereditary information to the next generation
- 2. a form of gene that is expressed as the trait when a dominant allele is present
- 3. a random change in an organism's DNA; can have a positive, negative or neutral effect on the organism
- 4. variations of genes that determine traits in organisms; the two corresponding alleles on paired chromosomes constitute a gene
- 6. the specific way a feature is expressed in an individual organism; for example, blue and green eyes
- 7. the passing of traits from parent to offspring
- 8. the basic unit of heredity carried by the chromosomes; codes for proteins which determine the traits of an organism
- 10. an organism's particular genetic makeup
- 13. a structure, characteristic, or behavior of an organism, such as eye color, plant height, or timing of migration
