3. The basic physical and functional unit of heredity made up of DNA
4. two identical alleles at a particular gene
7. A characteristic of an organism; can be genetic or acquired
8. a variation of a gene that will produce a certain phenotype, even in the presence of other alleles
10. Square, a helpful tool that helps to predict the variations and probabilities that can come from cross breeding
11. having two different alleles of a particular gene or genes.
14. the set of observable characteristics of an individual
15. A change or damage in the DNA that permanently alters the genetic message that the gene carries
16. Variation, The variety of gene combinations that exist within a population
17. The basic structural and functional unit of living organisms
18. Reproduction, The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves

1. A single, highly organized and structured piece of DNA
2. the genetic makeup of an organism
5. Different forms or versions of something
6. Biomolecules made up of amino acids and found in all living cells that perform bodily functions
