"Larkey Natural Selection: Computer Simulation"
Bellwork:
1) True or false?: recessive alleles have more influence on an organism’s traits.
2) A gene will increase in a population if it is ______________ for the organisms.
3) Puppies of a Ww (white) dog and a ww (black) dog will have ________________ -colored fur.
- Review Wed/Thurs activity
- Complete larkey "natural selection" simulation from FOSS Media Website (username: cheetah, password: 112)
- Complete workbook page 129: record computer simulation data and answer analysis questions
- Notes:
Adaptations in the forest and the prairie are different ==> different adaptations help the larkeys survive in these 2 different environments.
Over time, particular traits disappear because they are unhelpful (the larkeys with these traits get eaten and can't pass them on). Other traits increase because they are adaptations - these larkeys survive, reproduce, and pass on their traits so they don't go extinct.
