4. Can your genetic code be influenced by your environment?
Essential Question
Can your genetic code be influenced by your environment?
Standard
B.6D – Recognize that gene expression is a regulated process

5. Temperature & Gene Expression

6. Water level affects the size of the leaves.
Phenotypes are always affected by their environment. In buttercup (Ranunculus peltatus), leaves below water-level are finely divided and those above water-level are broad, floating, photosynthetic leaf-like leaves. Siamese cats are darker on their extremities, due to temperature effects on phenotypic expression. Expression of phenotype is a result of interaction between genes and environment. Siamese cats and Himalayan rabbits both animals have dark colored fur on their extremities. This is caused by an allele that controls pigment production being able only to function at the lower temperatures of those extremities. Environment determines the phenotypic pattern of expression.
Leaves above water are broad, below the water-level are finely divided

7. pH affects color. Acidic soil produces blue flowers and Alkaline soil produces pink.

8. HW - Twin Studies Video Quiz Tomorrow over T/T and Video
What is the genetic make up of identical twins?
What have we found out about the expression of the genes in twins?

9. In 1917 the biologist Thomas Hunt Morgan conducted studies in which he kept some caterpillars in the dark and placed other under red, green, or blue lights. Exposure to red light produced butterflies with brightly colored wings. Exposure to green light resulted in dark-colored wings. Exposure to blue light or no light resulted in pale-colored wings. What was the most likely conclusion of Morgan’s research?
The pigment in butterfly wings absorbs light from the environment
The phenotypic expression of wing shape depends on color pigmentation in butterflies.
The genes regulating wing color in butterflies are influenced by environmental factors.
Caterpillars exposed to red and green light are healthier than caterpillars exposed to no light or blue light.
