We looked at evidence from finch beak sizes to evaluate natural selection as an evolutionary mechanism. Natural selection is considered a deterministic process, one that yields predictable results. ...

Introduction to Genetics
... • Each trait has two alleles (versions). Plant height: Tall (T) or Short (t).. • These alleles segregate, or separate when gametes (egg and sperm) are formed. TT makes T gametes, Tt makes T gametes and t gametes.. • The allele from a sperm and the allele from the egg is the organism’s genotype. TT, ...
