Across
- 3. a thread-like structure inside a cell's nucleus that carries genetic information, made up of DNA tightly coiled around proteins, which passes on traits from parents to offspring
- 5. a genotype where an organism has two copies of a dominant gene
- 7. the process of passing genetic information, or traits, from parents to their offspring through genes carried in sperm and egg cells
- 11. the basic physical and functional unit of heredity
- 12. the genetic makeup of an organism, or the specific combination of alleles inherited from its parents
- 13. the passing on of genes and genetic traits from parent to offspring
- 14. A diagram of family history that uses standardized symbols
- 15. a variant of a gene, or one of the alternative forms of a genetic sequence on a chromosome
- 17. the differences between individuals of the same species, caused by genetic and environmental factors
Down
- 1. an organism with two copies of the same recessive allele for a trait
- 2. a diagram used in genetics to visually show all possible combinations of alleles (genes) from two parents
- 4. produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent
- 6. the observable traits of an organism, such as its physical appearance, behavior, and biochemical properties
- 8. A scientist who has special training in the study of genes and heredity
- 9. A term that describes having two different versions of the same gene
- 10. a gene that is not expressed when paired with a dominant allele
- 16. a specific characteristic of an individual
