lifestyle
• Green Iguanas are forest dwelling lizards that live high in the tree canopy of the South American rainforest.
• Young iguanas stay in areas lower in the forest canopy. Mature iguanas live higher in the tree tops. Iguanas rarely leave the trees. The only real exception to this is when the female iguanas must come down from their sky high home in order to dig burrows in which the female iguanas lay their eggs.
• Iguanas prefer to have water around them as iguanas are excellent swimmers and will often dive beneath the water to avoid oncoming predators.
MUTATIONS… all are super-dominant
• 1. no mutation • 2. “N” Nostril genes mutate during meiosis. The
new gene causes glands in the nose to collect extra salt from the blood and to expel that salt.
• 3. “B” mutation of skin pigment gene causes black pigment instead of green
• 4. “S” Mutation of foot shape gene on chromosome 2 causes webbed feet
• 5. “C” The “calm gene” is a Mutation of the fear reaction gene on chromosome 3. The calm gene causes fear reaction to dissapear.
IF you missed it
• The iguana tsunami activity is designed to get your thinking about how a population of iguanas might change over time if they are “dropped” into a new environment.
