Black and white rabbit on black part of ravvit on ears : the termperature of the extremeties is lower and allows expression of the black coat colour gene. On white part of body: the temperature of most of the body is too high for the expression of the black coat colour gene genotype environment interactions.

Life stressors that were captured included change in employment, housing, finances, health, and relationships, and individuals were asked about depressive symptoms including thoughts of suicide, suicide attempts, or a diagnosed depressive episode.
