2What is a locus?
- AA "fixed address" on a chromosome
- BA cicada
- CA "street map" for where certain genes are on the chromosomes
3What is an allele?
- AA group of genes that determine a trait

- BB101
- CAll about that bass
6Blood Type O allele

- BFor example, what color socks you buy
- CFor example, blood type
11Poly-genic phenotypes are...
- AAlleles at two or more loci
