Across
- 5. the study of how traits are passed from parents to offspring
- 7. how a trait appears or is expressed
- 9. the alleles of all the genes on an organism's chromosomes; controls and organisms' phenotype
- 10. a genotype in which the 2 alleles of a gene are the same
- 11. a different form of a gene
- 12. a genetic factor that blocks another trait
Down
- 1. the passing of traits from parents to offspring
- 2. a section of DNA on a chromosome that has genetic information for one trait
- 3. a genetic factor that is blocked by the presence of a dominant factor
- 4. a genotype in which the 2 alleles are different
- 6. this 4 box model is used for showing potential genotypes for alleles
- 8. a model that show genetic traits that were inherited by members of a family
