This month's issue of
National Geographic magazine features a
cover story about the "Spirit Bears" of British Columbia. "Spirit Bear" refers to the Black Bears that are white in color due to a recessive trait called Kermodism. As always the National Geographic website has some neat resources to support the main article. One of the online resources for the
Spirit Bear article is a
Punnett Square that explains how two black Black Bears can produce a white Black Bear.
On a related note, National Geographic has a short video about photographing Polar Bears in their natural environments that you might find interesting. The video is embedded below.
Applications for EducationThe story of the Spirit Bear could provide a good backdrop to an introductory lesson in genetics.
