IB Biology SL Paper 1 Biology Quizizz. The colour of fur in Himalayan rabbits is affected by a gene which is only active at cooler temperatures (15°C to 25°C). If a Himalayan rabbit is reared at 20°C it has dark coloured fur on its ears, nose, and feet. At 30°C the gene is not expressed and so a Himalayan rabbit living in warmer climates has white fur on these parts.
