7. A variant of a gene that can produce different versions of the same trait.
8. The physical expression of an individual's genotype, which includes observable traits.
9. A segment of DNA that contains instructions for a specific trait.
13. A disease or condition caused by an abnormality in an individual's DNA.
14. -Replication The process by which DNA makes a copy of itself before cell division.
15. The genetic makeup of an individual, which determines its traits.

1. A structure made of DNA that carries genetic information.
2. A diagram used to predict the possible outcomes of a genetic cross.
3. A change in the DNA sequence that can alter the function of a gene.
4. The passing of genetic information from one generation to the next.
5. Differences in the DNA sequence among individuals that can affect their traits.
6. Having two different alleles for a particular gene.
10. A gene that is only expressed when two copies are present.
11. A gene that is always expressed when present, even if only one copy is present.
