Two versions of the same allele (same as purebred) Example: GG or gg __heterozygous___ 6. Different versions of an allele (same as hybrid) Example: Gg or Tt __reproduction___ 7. Production of offspring by combining of a sperm cell and an egg cell. _fertilization__ ___8. What is the name of the process when an egg and sperm join? 8. Place the letter of each characteristic in the correct area of the Venn Diagram. A) Genetic material passed to offspring B) one parent C) two parents D) offspring are not identical E) offspring are identical to each other F) genetic variation and to the parent G) Produce offspring H) faster process Use your Genetics Notes for the following questions.9. In sexual reproduction, each parent contributes __half____ of the offspring’s genetic information. 10. In humans how many chromosomes are present? __46_______ How many chromosomes came from the egg cell? __23______ How many chromosomes came from the sperm cell? ___23_____ Asexual Reproduction Sexual Reproduction A B E G C D H F
11. DOMINANT + DOMINANT = __DOMINANT________________ trait 12. DOMINANT + recessive = ____DOMINANT______________ trait 13. recessive + recessive = ____recessive________________ trait 14.Using the letter R, write a genotype to represent purebred. __RR or rr_________15.Using the letter B, write a genotype to represent hybrid. ___Bb__________16.What are dominant traits represented by? ______capital letter_____________________ 17.What are recessive traits represented by? _____lowercase letter_____________________ Use the following information and then answer the questions that follow it.▪Brown hair is dominant to blonde hair. Bob is a hybrid (heterozygous) for Brown hair. His wife Bobbie Sue is purebred (homozygous) for blonde. 18. Phenotype of Bob: __brown_______ Phenotype Bobbie Sue: __blonde_____ Genotype Bob: __Bb___________ Genotype Bobbie Sue: __bb_______ Label each of the following examples as a product of Asexual or Sexual Reproduction. A=Asexual B=Sexual Reproduction 19. ___A_____ Hydra budding 20. ___B____ Kitten 21. ___A____ One-celled bacteria dividing 22. ___B____ wildflower blooming in the Spring! 23. ___A____ Potato budding in the pantry In the picture below, circle what type of reproduction is occurring. READ24.25.26.27.
●Use the reproduction pictures from above to answer questions #28-29.28. Which of the examples of reproduction would result in offspring that are identical? Explain…#24, #26, #27: Genetic material is only being passed on to the offspring by 1 parent and no genetic variation in the offspring. 29. Which of the examples of reproduction would result in offspring that are diverse? Explain… #25: Genetic Material combined from 2 parents 30.Which would be considered an inherited trait (circle the ones below that would be inherited)? ●Lateness ●Not liking vegetables ●Dimples ●Blood type ●Broken bone 31.Mutations are the changing of the structure of a gene or a chromosome that makes it different than the parent cell type it was inherited from. Mutations can be harmful or helpful. Do all mutations have an effect on an organism? No. Not all mutations have an effect on an organism.
32.Complete the flow map of the organization of our Genetic Information below: 33.Identify the following as homozygous or heterozygous: TT=____homozygous________________________________ Tt=_____heterozygous___________________________________ tt=______homozygous__________________________________ 34.Where in the cell would you find DNA? _____Nucleus_________________________________________ Cell Chromosome DNA Gene Trait
35.Natural Selection or Selective Breeding: Answer the following descriptions with the correct*Also known as Artificial Selection: _____Selective Breeding______________________________*Also known as Survival of the Fittest: ____Natural Selection_____________________________*Having the best traits to survive and thrive in an environment to be able to pass down to future generations: ___________Natural Selection_______________________*Humans select the best traits to use for an organism: ____Selective Breeding_____________*Slow process: _______Natural Selection_________________________________________________*Faster process: _______Selective Breeding________________________________________________Natural Selection_______ _____Selective Breeding____________ 36.Traits that help an organism survive in an environment are called: __adaptations_________37.Identify each trait as a physical or behavioral adaptation: *hibernation: ____behavioral adaptation______________________________ *burrowing: ___behavioral adaptation_______________________________ *thick fur: ____physical adaptation________________________________ *colorful flowers: ___physical adaptation__________________________ 38.What is the purpose of DNA? __to provide the instructions of genetic information for the cell__ 39.What is genetic variation? Naturally occurring genetic differences among organisms in the same species.40.Which type of reproduction will have (natural) genetic variation and explain? ____Sexual Reproduction because it involves the combining of traits from two parents.___ ***The questions on this study guide are the topics that will be covered on the assessment. ***There will be questions on the assessment that will involve more reading to solve problem, choose all that apply options, multi-part and two-step questions. ***You will really need to know your information and be able to apply the concepts successfully. ***Please utilize the helpful tools on Schoology Assessment if needed for ysuccess (text to speech, eliminate answers of your choosing, flag questiofor review, etc.).
