Name __________________________________________ Class ____________ Date _______________ Turtle-Mania Genetics-PreAP Purpose: to understand how genetic information is passed from parent to offspring. You are about to select trait combinations for certain traits of a turtle. For each trait in the table below, flip a coin. 1st-Flip the penny for the traits that the new baby turtle will receive from the mother turtle 2nd-Flip the nickel to determine the traits that the new baby turtle will receive from the father turtle. If you get “heads” then put down a “capital” letter for the dominant trait. If you get “tails” then put down a “lower case” letter for the recessive trait. 3rd-Then in the next column, combine the traits from the mother and father. These are the trait combinations for the new baby turtle. 4th-In the final column write down what physical trait should appear in the baby turtle. Traits Genes Shell Color: Light green= G Dark green= g Striped= S Boxed=s Shell pattern: Traits from Mom turtle Traits from Dad turtle Baby turtles new Physical Trait Trait Combination that baby shows Tail shape: Straight=C Curly=c Nose shape Pointy=P Round=p Skin color: Green with spots=R Green with stripes=r Neck length: No neck=N Long neck=n Type of Flippers =F legs: Feet with claws=f Nose Warts: Wart with hair=W No wart or hair=w Eye color: Brown eyes=B Blue eyes=b Tongue Forked shape: tongue=T Flat tongue=t Conclusion Questions **FIRST draw your turtle in the box on the bottom of the second page. THEN answer the following questions. 1.The passing of traits from parents to offspring is called ___________. 2.Where did your turtle get his traits from?________________ 3.Does your turtle look exactly like his/her parents?___________________ 4.Explain why it does or why it does not look exactly like his/her parents. ______ _____________________________________________________________ _____________________________________________________________ 5.What type of reproduction occurred in today’s lab?_________________ 6.A long thin strand that contains hereditary information is called ______. 7._______ is coiled and makes up _____________ that contains your turtles characteristics. 8.If we were to look at one of your turtles cells, where could we find it’s genetic traits?______________ 9.Explain how dominance played a part in today’s lab.______________________ _____________________________________________________________ _____________________________________________________________ 10. If you were a person who raised turtles and you wanted to have turtles who all had a light green shell, what might be something you could do to solve this problem?______________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 11. What is the name of the process that you are using in question number 10?_____________________________ Draw your turtle in this box. It cannot be any bigger than this box. We will be hanging these drawings up in the hall so make sure to do your best work!
