IS SEMESTER ONE ALMOST OVER?
DATA BASED QUESTIONS
a) Lassen County: 83.3% ; Santa Cruz: 15.4%
b) In Santa Cruz, the snakes began to eat more slugs while the snakes in Lassen County started to eat less slugs. However, as population grows, the competition also grows in environments, which is what happens in Lassen County. There are fewer slugs, so the competition is very intense as the snakes have to fight over their food supply.
2. Lassen County snakes will outcompete te Santa Cruz snakes because of natural selection!
a) Over the course of time, natural selection will make it so that the slug eating response isn’t inherited, so less snakes ate slugs.
b) Because natural selection selected against the slug eating allele, as time passes, the allele will become recessive. The snakes wouldn’t be able to survive if the allele were dominant because they’d naturally try to hunt for slugs, and because the environment doesn’t have that supply, they would suffer.
