GENETICS

3. The molecule carrying genetic instructions for development, functioning, and reproduction.
4. An allele that masks the presence of a recessive allele in the phenotype.
7. An allele that only expresses its characteristic trait when paired with another recessive allele.
8. A structure made of tightly coiled DNA found in the nucleus of cells.
10. The passing of traits from parents to offspring.
11. A variant or different form of a specific gene.
12. Having two identical alleles for a specific gene.
14. The branch of science studying heredity and the variation of inherited characteristics.

1. A diagram used to predict the possible genotypes and phenotypes of offspring.
2. A permanent change in a gene or chromosome sequence.
5. The observable physical expression of an organism's genes.
6. The genetic makeup or combination of alleles of an organism.
9. A specific characteristic of an organism, such as eye color or height.
10. Having two different alleles for a specific gene.
13. A segment of DNA that acts as the basic unit of heredity and contains instructions for making proteins.
