2.2.One example is the of the sea turtles depends on both on genes and on environment. Female turtles make nests on beaches and bury their eggs in the sand. Eggs that mature in warmer temperatures develop into female turtles. Eggs that mature in cooler temperatures develop in male turtles.Another example is markings on siamese cats. the amount of the dark colour appearing is temperature dependent and increases in cooler climates. so if you take a siamese cat from a hot climate to a cool climate there will be more dark colour in its points (although it may take up to 2 years for this to be evident as the original coat needs to grow out) this is also why the dark colour appears on the extremities - these regions are a slightly lower temperature than the central body region. Last example is the studies of identical twins have shown that the environment during early development can have long lasting effects. One twin might get more nutrients than the other because of its positions in its mother's uterus. The difference can result in height and size differences that last throughout the twins' lives.Also, twins raised in environments with different nutrition and health care often differ in height and other physical traits.
