- 3. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
- 4. a hybrid that is heterozygous for alleles of two different genes
- 5. has two identical alleles of a particular gene or genes.
- 6. the deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent
- 8. embryos"
- 11. a trait that is expressed only when genotype is homozygous
- 13. found in the inner cell mass of the human blastocyst
- 14. the inheritance of a trait governed by more than one genes
- 15. an offspring of two animals or plants of different subspecies, breeds, varieties, species, or genera
- 17. the passing on of physical or mental characteristics genetically from one generation to another
- 18. the inheritance of traits that are typically passed vertically from parent to child where both the parent and the child are affected by the trait or disorder that is related to that gene.
- 19. describes how different genes independently separate from one another when reproductive cells develop
- 20. an ancestral line
Down
- 1. immature cells that are able to make other blood cells that mature and function as needed
- 2. has two different alleles of a particular gene or genes.
- 6. a person who can pass an inherited (genetic) disease on to their children but who does not have the disease
- 7. three or more possible alleles for one individual trait
- 9. is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding
- 10. the genetic constitution of an individual organism
- 12. is a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual
- 16. The phenomenon in which two true-breeding parents crossed to produce an intermediate offspring
