- 3. a characteristic, such as height or skin color, that is influenced by two or more genes.
- 12. having two different alleles of a particular gene or genes
- 13. a group of organisms that are born around the same time and are the next line of descent.
- 14. a genetically determined characteristic (blue eye color, red hair color)
- 15. the process of passing genes from parent to offspring
- 16. traits that organisms gain through experiences
- 17. a quantitative amount that predicts how likely something is to happen. (A 1 in 4 chance of stubbing your toe)
- 19. the study of how traits are passed from parent to offspring
- 21. a chart that diagrams the inheritance of a trait of health condition through generations of a family. Can be used to trace traits and diseases.
- 23. Mendell known as the “Father of Genetics” for his discovery of inheritance in pea plants.
- 25. abbreviation for deoxyribonucleic acid, the molecule that carries genetic information for the development and functioning of an organism.
- 26. a square diagram that is used to predict the genotypes of the next generation in a particular cross
- 27. sequence the order of nucleotide bases in DNA that give the instructions for cells to develop and operate.
- 28. specific patterns of how traits are passed from parent to offspring, established by Gregor Mendel
- 29. characteristics that are passed down through generations through either the X or Y chromosomes
Down
- 1. having two of the same alleles of a particular gene or genes
- 2. the passing on of traits from one generation to the next
- 4. a form of gene interaction where both alleles are partially expressed, resulting in a new
- 5. the gene that will only be expressed if it is inherited from both parents
- 6. the set of genes that are carried by an organism and determine its phenotype
- 7. the gene that will always be expressed in a trait, even if it is inherited from only one parent
- 8. a change in the gene sequence of an organism that occurs during cell division.
- 9. one of a pair of genes that determine a specific trait and is inherited by the parent generation
- 10. the type of inheritance where both alleles are dominant and are expressed equally in an organism.
- 11. the set of observable characteristics of an individual
- 18. a quantitative amount that shows how many times one number contains another. (There are 8 oranges in a bowl of 15 fruit. The ratio is 8/15)
- 19. segment of DNA, found on a chromosome that determines the inheritance of a particular trait
- 20. a quality belonging to a person, place, or thing (eye color, hair color)
- 22. any pattern of inheritance that does not adhere to Mendel’s Laws of genetics.
- 24. the product of the reproductive processes of an organism.
