For this natural selection story, focus on just ONE GENETIC TRAIT that has two alleles. This is a make-believe story but the story line should sound plausible. Do not involve humans in any way. Once upon a time there was a population of polar bears. Most of the polar bears had/were_(a)___ but a small proportion of the population had/were__(b) ___ Over many generations, the proportion of bears expressing the rare allele became more common through natural selection. What was going on within this population to cause this shift? ___(c)_(very brief is great!) Note: do NOT mention whether the alleles are dominant/recessive nor about individuals being homozygous etc. We are looking at the big picture population-level patterns only.
