Genetics

2. the study of heredity and the variation of inherited characteristics.
8. containing two complete sets of chromosomes, one from each parent.
9. the offspring of two plants or animals of different species or varieties.
13. a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
14. a genetic situation in which one allele does not completely dominate another allele.
16. record of the DNA sequence of a gene.
18. a word that refers to a particular gene that has identical alleles on both homologous chromosomes.
19. the separation of pairs of alleles at meiosis and their independent transmission via separate gametes.
20. a distinguishing quality or characteristic, typically one belonging to a person.
21. a mature haploid male or female germ cell.

1. a relationship between two versions of a gene.
3. the parents will also pass down a specific phenotypic trait to their offspring.
4. a series of three or more alternative or allelic forms of a gene.
5. process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other.
6. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
7. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
10. a basic principle of genetics developed by a monk named Gregor Mendel in the 1860's.
11. relating to or determined by polygenes.
12. similar in position, structure, and evolutionary origin but not necessarily in function.
15. a scientific prediction being true.
17. a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
