Genetics

1. This is the molecule inside cells that carries all the instructions for how an organism grows, looks, and functions.
7. A characteristic you can see or measure in an organism, like eye color or height.
10. A change in DNA that can sometimes affect traits and create variation.
14. Structures inside the cell nucleus that carry genes and DNA.
15. Another word for different versions of the same gene.
16. The physical appearance or observable trait that results from the genotype.
17. This type of gene version only shows up if both copies are the same, otherwise it’s hidden.

1. This type of gene version hides the other version and shows up in the organism even if there’s only one copy.
2. When offspring receive DNA from their parents, passing traits from one generation to the next.
3. – The parts of DNA that form the “backbone” of the molecule, holding it together.
4. Molecules made by cells that do jobs like building muscles, carrying oxygen, or fighting germs. DNA instructions tell cells how to make these.
5. When an organism has two different versions of a gene for a trait.
6. The letters of the DNA code (A, T, C, G) that pair up to store genetic information.
8. When an organism has two identical versions of a gene for a trait.
9. The combination of alleles an organism has for a specific trait.
11. Two nitrogen bases that always pair together in DNA (A with T, C with G) like puzzle pieces.
12. A segment of DNA that controls a specific trait in an organism.
13. Differences in DNA that make individuals of the same species look or behave differently.
