Genetics

3. the study of heredity and the variation of inherited characteristics
4. the genetic constitution of an individual organism
5. a relationship between two versions of a gene. Individuals receive one version of a gene
6. a pair of matching alleles, which are the two genes that control a particular trait
7. the extent to which something is probable; the likelihood of something happening or being the case
12. have a commanding influence on; exercise control over
13. bred from parents of the same breed or variety
14. Square diagram that is used to predict an outcome of a particular cross or breeding experiment
15. a distinguishing quality or characteristic, typically one belonging to a person

1. relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent
2. refers to a pair of genes where one is dominant and one is recessive
6. the offspring of two plants or animals of different species or varieties
7. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
8. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
9. dominance a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype
10. the passing on of physical or mental characteristics genetically from one generation to another
11. a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
