speciation stories the next time we meet.

We will go over the speciation stories the next time we meet, then the next day a review, then the test. Have a fictional story of speciation and the process done for tomorrow. It should be complete with before and after pictures and an explanation of the process. there will be a test by Monday or Tuesday. Thanks, Mr. Worden

class work for Friday take this quiz about the mouse movie from the homework

mouse movie quiz You can use your ipad to go back and look at the movie. You may work with a partner to solve the problems. you may use your text or online sources. If true then write T, if False then write false and what the truth is! 1. T or F individual brown mice that move onto the black lava turn black so they are camouflaged. 2. T or F Researchers found that all the mice collected at the lava flow were black. 3. T or F Mice that were brown prefered to be on the desert sand instead of the lava flow so they would not be seen. 4. T or F the differential reproductive success of black mice was due to black mice refusing to mate with brown mice. 5. T or F In this case if black mice make up most of the population on the lava, this indicates that the inheritance pattern must be black is dominant and brown is recessive. 6. T or F A nearby population of the same species of mice living on the desert sand are mostly brown. this means the brown allele be dominant and the black is recessive. 7. T or F If black mice on the lava have a 10% Differential reproductive success, then it would take a million years for 90% of the population to be black. 8. T or F the Natural selection for black fur on mice affected the color of the top of the mouse, but not the change of color in the bottom of the mouse. 9. T or F a mutation in a gene causes the change from brown fur to black fur 10. T or F In other parts of the state where there is lava they found that mice changed color by rubbing up against the lava to become darker choose 11. If there are many shades of brown and many shades of black, then this trait is probably... Sex-linked / polygenic 12. If all the predators were exterminated then the population that is mostly black would... Stay the same/ turn back to mostly brown 13. If black is recessive, and six black mice are brought to an island with no other mice, then the only way to make a brown mouse is by... random fertilization/ mutation 14, Dr Saft is a(n)... evolutionary biologist narrating the movie/and acronym for natural selection 15. Mutiacorf is a way to remember... how natural selection affects populations/ways of variation in the offspring
