- 2. Square A chart that shows all the possible combinations of alleles that can result from a genetic cross
- 4. Parental generation, the first two purebred individuals that mate in a genetic cross
- 5. one of a number of different forms of a single gene
- 9. An organism that has two identical alleles for a trait
- 10. An organism's genetic makeup, or allele combinations
- 12. Law that states that a recessive allele will always be masked by a dominant allele.
- 14. Passing of traits from parents to offspring
- 15. Augustinian monk and botanist whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics (1822-1884)
- 16. An allele that can be hidden whenever the dominant allele is present
- 19. the first generation of offspring obtained from an experimental cross of two organisms
- 20. Cross A genetic cross in which only one trait is tracked
Down
- 1. An organism's physical appearance, or visible traits.
- 3. An organism that has two different alleles for a trait
- 6. Assortment Mendel's second law, stating that allele pairs are not linked and separate independently from one another during gamete formatio
- 7. An allele whose trait always shows up in the organism when the allele is present.
- 8. An organism that always produces offspring with the same form of a trait as the parent. Often also called a "true-bred"
- 11. Characteristics that are inherited
- 13. the second generation of offspring, obtained from an experimental cross of two organisms; the offspring of the F1 generation
- 17. of Segregation Mendelian law stating that two alleles for each trait separate during meiosis
- 18. The field of biology that studies heredity
- 21. Offspring of crosses between parents with different traits
- 22. Cross A genetic cross in which the inheritance of two traits are tracked at the same time.
