x-inactivation in tortoiseshell cats
Posted: Wed Aug 14, 2019 2:19 pm
I am doing the science project on x-inactivation in tortoiseshell cats to determine if the display of black/brown vs orange/red is random or pre-determined. Female cats have two x chromosomes of the orange coloring allele and only one can be active at a time. If the O out of the Oo is active, the area will have orange/red fur, and if the o out of Oo is active, it will be black/brown.
I think my independent variable is the pictures of 15 female tortoiseshell cat faces divided into 12 areas while the dependent variable is charting if the pattern is random or pre-determined among the pictures.
As I do not need to control the environment in this experiment, like temperature, light, etc., what would be a control, (ex. 12 week or older female cats)? Also, would constants be that all the cats are female tortoiseshell cats with no other color fur, same camera angle, etc. ? I am a bit confused on that as my experiment is different than ones I have done before.
