Across
- 4. Segments of DNA on a chromosome and are responsible for inherited traits.
- 5. Skin , hair , and eye color , height , and freckles
- 8. The physical appearance of an organism or the trait that you see, which is dependent on the genotype
- 13. a random error in gene replication that leads to a change
- 15. Variants in a gene , In humans , might indicate blood type, colorblindness, or many other traits
- 17. The study of heredity , which is a biological process where a parent passes certain genes onto their offspring
- 20. A characteristic that is passed from parent to offspring
- 21. Stores the cells hereditary material or DNA ,Controls most of the cell's activities
Down
- 1. The genetic makeup of an organism
- 2. Carries two different alleles
- 3. An organism that always produces offspring with the same form of a trait as the parent Homozygous
- 6. Genetically determined characteristics
- 7. Describes a trait that covers over, or dominates, another form of that trait, Show their effect with only one copy of the allele
- 9. A trait that is not in your genes but is picked up from environmental factors .
- 10. carries the same two copies of the same allele
- 11. an allele that is masked when a dominant allele is present , Show their effect with two copies of the allele
- 12. A molecule that contains all genetic instructions for living organism .
- 14. a diagram used by geneticists to determine the probability of an offspring having a particular phenotype
- 16. An organism that has two different alleles for a trait , Heterozygous
- 18. Thread-like structures that are found in the nucleus of a cell that contains all DNA
- 19. Father of modern genetics , discovered the basic principles of heredity , and experimented on pea plants and showed that their traits follow a particular pattern
