Across
- 8. production of a phenotype that is intermediate between two homozygous parents
- 9. outward physical appearance and behavior aof an organism
- 10. an alternate form that a gene may have for a single trait; can be dominant or recessive
- 13. A diagram that shows the occurrence of a genetic trait in several generations of a family.
- 14. These structures are found in the nucleus of a cell that contains DNA. "Package for the DNA"
- 19. a tool to predict the probability of certain traits in offspring that shows the different ways alleles can combine
- 20. Segment or section of DNA that code for a particular trait. Made up of two alleles.
Down
- 1. Cell division that produces reproductive cells called gametes
- 2. decribes an organism with two alleles that are the same for a trait
- 3. describes a trait that is covered over, or dominated, by another form of that trait and seems to disappear
- 4. An organism or cell having only one complete set of chromosomes.
- 5. cell division that results in two identical a cells
- 6. Reproductive cells that are haploid (n), also known as sperm and eggs
- 7. biological and chemical methods to change the arrangement of a gene's DNA to improve crop production, produce large volumes of medicine, and change how cells perform their normal functions
- 11. Double helix; found in the nucleus and contains genetic information
- 12. an organism's genetic makeup
- 15. describes an organism with two different alleles for a trait
- 16. a new organism produced by parents (seedling, child, kitten)
- 17. An organism or cell having two sets of chromosomes or twice the haploid number
- 18. decribes a trait that covers over, or dominates, another form of that trait
