1. Explain why race is not a valid biological classification for humans.
the criteria for race is based on phenotypes- such as skin color, facial features, and
hair form that can differ between native inhabitants of different regions of
Gene pool- the total genetic information encoded in all the genes in a
breeding population existing at a given time
Genes- unit of inheritance carried on a chromosome in gametes affects
development of individual
Alleles- different forms of a single gene
