Rewilding and Food Sustainability

Rewilding is a conservation approach that focuses on restoring natural processes. It involves less human management compared to many approaches to managing landscapes including both natural and agricultural areas. Keystone species, those that impact many other species, are fundamental to the success of rewilding, as is the return of wild versions of both plants and … Continue reading

Intergenerational trauma impacts gene expression

I say it this way because, in talking with individuals from First Nations communities the trauma of both first hand … Continue reading

Cat Genetics Activities

Since most of the questions ask you to cross a cat that you found there is no answer key. Teachers, please feel free to use this activity in … Continue reading

The making of a tabby cat

I’ve found it quite fascinating to look into cat genetics over the past week. I should have my entire planned activity for my bio students to share by next week, but in the meantime I thought I’d write about the agouti and tabby genes. The presence of a dominant agouti gene affects pigment distribution along … Continue reading

Cat Genetics

I’m teaching a bio course this term and I’ve been looking for ways to engage students in lab type activities given that we can’t go into a lab. When someone sent me an article about why most of the human genetic traits we like to use in genetics lessons are inaccurate I was, shall we … Continue reading

What does it mean to be a carrier?

One of the things that my biology students often struggle with is what exactly does it mean to be a carrier for a particular trait. This is a difficult concept because it seems odd that we might have the information in our DNA for a trait such as a disease but we don’t actually have … Continue reading
