Genetics

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

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
