Heredity & Genetics

2. A segment of DNA on a chromosome that codes for a specific trait
5. The process in which genetic material is passed from parents to their offspring.
6. An organism's combinations of genes that determine their characteristics
8. Threadlike structures made of DNA molecules that contain the genes.
9. A molecule containing the genetic information that makes up the chromosomes found in the nucleus of every cell
10. The female reproductive cell that has half the amount of chromosomes as a body cell
11. A diagram that shows the occurrence of a genetic trait in several generations of a family.
13. The male reproductive cell that has half the amount of chromosomes as a body cell
14. Area where the chromatids of a chromosome are attached
16. A chart that shows all the possible combinations of genes that can result from a genetic cross
17. The part of the cell containing DNA
19. The trait observed when at least one dominant gene for a characteristic is inherited
20. An organized display of the chromosome pairs of a cell arranged by size and banding pattern.
21. A characteristic that an organism can pass on to its offspring through its genes.

1. Specialized body cell that produces sperm
3. A change in a gene or chromosome.
4. A trait that is apparent only when two recessive genes for the same characteristic are inherited
7. Augustinian monk and botanist whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics (1822-1884)
12. Process in sexual reproduction in which male and female reproductive cells join to form a new cell
15. Specialized body cell that produces eggs
18. A person whose genetic code includes a gene that is not expressed in that person, but can still pass it on to their offspring.
