Across
- 1. the relationship between two versions of a gene
- 4. a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells
- 6. a reproductive cell of an animal or plant
- 10. having different alleles for a particular trait
- 12. one of two or more alternative forms of a gene
- 13. a characteristic, such as height or skin color, that is influenced by two or more genes
- 14. how different genes independently separate from one another when reproductive cells develop
- 15. a trait that is expressed only when the genotype is homozygous
- 19. a square diagram that is composed of a grid of usually four boxes
- 20. diagram of family history that uses standardized symbols
- 21. distinguishing quality or characteristic
- 23. the genetic constitution of an individual organism
- 24. an inheritance pattern where two alleles are expressed equally, and neither allele is dominant or recessive
Down
- 2. a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype
- 3. the set of observable characteristics of an individual
- 5. any observable feature, or trait, of an organism
- 7. certain patterns of how traits are passed from parents to offspring
- 8. structure of nucleic acids and protein
- 9. the presence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair
