Genetics

5. A characteristic that an organism can pass on to its offspring through its genes
6. When both genes are the same and the genotype has both capital or both lowercase letters: AA, aa, BB, bb
8. Describes a trait that covers over, or dominates, another form of that trait. It is written as a capital letter
10. Diseases whose risk increases through many different genes acting
11. Autosomal recessive - skips a generation
12. The genes that are present in an organism: Aa, AA, aa

1. When an individual is made up of populations of cells with different genetic constitutions e.g calico cats x chromosome inactivation leads to orange and black fur
2. The characteristic you see: blue eyes, brown eyes, curly hair, straight hair
3. The passing of traits from parent to offspring
4. When the genes are different and there's one dominant gene with a capital letter and one recessive gene with a lowercase letter: Aa, Bb, Dd, Rr
7. A segment of DNA on a chromosome that codes for a specific trait
9. an alternative or different form of gene
