Across
- 2. father of genetics
- 3. when both alleles can be observed in a phenotype
- 5. when the two alleles of a gene are different
- 7. trait that is blocked by the presence of a dominant factor
- 8. how a trait appears or “is expressed”
- 14. the study of how traits are passed from parents to offspring
- 17. different forms of the same genes
Down
- 1. when the offspring’s phenotype is a combination or blend of the parent’s phenotypes
- 2. the two alleles that control the phenotype of a trait
- 4. deoxyribonucleic acid – an organism’s genetic material
- 6. a section of a chromosome that has genetic information for one trait
- 9. when the two alleles of a gene are the same
- 10. a distinguishing quality or characteristic
- 11. a model used to predict possible genotypes and phenotypes of offspring
- 12. trait that blocks another genetic factor
- 13. a molecule with a nitrogen base, a sugar, and a phosphate group
- 15. genetic cross between a homozygous recessive individual and corresponding heterozygote to determine the heterozygote’s genotype (PP x pP)
- 16. X-shaped structures located inside the nucleus of cells that contain the genetic information that controls traits
