Genetics
Across
- 4. when there is no allele that can block or mask the expression of the other allele
- 6. a structure made up of DNA, is found in the nucleus of each cell
- 8. a table where all of the possible outcomes for a genetic cross with two individuals with known genotypes are given
- 10. the basic unit of heredity passed from a parent to the child
- 11. a cell that only contains one set of chromosomes
- 12. a trait that can be masked by stronger traits
- 13. an individual observable trait like eye color and hair color
- 16. when you inherit the same version of a gene from each parent (have two matching genes)
- 20. a cell that contains two sets of chromosomes
- 21. when different types of genes independently separate from one another when reproductive cells develop
- 22. certain patterns of how traits are passed from parents to offspring
Down
- 1. a characteristic, such as height or skin color, that is influenced by two or more genes
- 2. where a dominant allele does not completely mask the effects of a recessive allele
- 3. a unique trait and characteristic
- 5. a type of cell division in sexually reproducing organisms that reduce the number of chromosomes in gametes.
- 6. a quality that an individual or group has different from others
- 7. family history that indicates which individuals have certain genetic traits, and diseases
- 9. genetic material that makes up someone's qualities, characteristics, traits etc. It is self replicating
- 11. when you inherit a different version of a gene from each parent
- 14. a characteristic of a person
- 15. any living cell other than the sperm and egg cells (reproductive cells)
- 17. a trait that is much more noticeable than others
- 18. one of two or more versions of a genetic sequence at a particular region on a chromosome
- 19. a reproductive cell of an animal or plant
