Across
- 3. an organism's complete genetic makeup, specifically the set of alleles it carries for a specific gene or all its genes
- 5. How scientists use genetic information to solve biological mysteries.
- 8. proposes that chromosomes are the carriers of genetic information, with genes located at specific positions on them
- 11. one copy of a recessive gene but no symptoms
- 13. pairs of chromosomes, one from each parent, that are similar in size, shape, and gene arrangement
- 14. a gene or trait that is only expressed if an organism inherits two copies of the allele, one from each parent
- 15. the different versions or flavors of a single gene
Down
- 1. a diagram used to predict the possible genotypes and phenotypes of offspring from a genetic cross between two parents.
- 2. the set of all observable physical or biochemical characteristics of an organism, such as eye color, height, and behavior
- 4. A term that describes having two different versions of the same gene
- 6. an allele that expresses its associated trait even when only one copy is present
- 7. a genetic cross that examines the inheritance of two different traits at the same time
- 9. a genetic phenomenon where the effect of one gene is masked or modified by one or more other genes, creating a non-additive relationship between genes and phenotype
- 10. an individual who has two identical copies (alleles) of the same gene, one inherited from each parent
- 12. a genetic experiment that studies the inheritance of a single trait by crossing two parent organisms that are heterozygous for that trait
