Presentation Transcript

  1. “Genetics Jeopardy”

  2. Meiosis: 1 point How many chromosomes are found in a typical human sperm or egg cell? 23

  3. Meiosis: 2 points What are the end products of meiosis? 4 haploid cells

  4. Meiosis: 3 points In this phase, homologous pairs of chromosomes line up along the equator. Metaphase I

  5. Meiosis: 4 points Meiosis is used to make cells for: • Sexual or • Asexual Reproduction? Sexual Reproduction

  6. Meiosis: 5 points When would crossing over in the cell most likely occur? When homologous pairs line up

  7. Mendelian Genetics: 1 point Organisms that have 2 identical alleles for a particular trait are said to be: Homozygous

  8. Mendelian Genetics: 2 points What did Gregor Mendel use pea plants to study? The inheritance of traits

  9. Mendelian Genetics: 3 points A homozygous tall pea plant is crossed with a homozygous short pea plant, and all the offspring are tall. What is the most likely genotype of the offspring? Tt

  10. Mendelian Genetics: 4 points Suppose and animal is heterozygous AaBb. When meiosis occurs, what is the total number of possible combinations of gametes that can be made for these traits? (FOIL) 4

  11. Mendelian Genetics: 5 points A white mouse whose parents are both white, produces only brown offspring when mated with a brown mouse. The white mouse is most probably _____________. • Heterozygous or Homozygous? • Dominant or Recessive? Homozygous recessive

  12. Complex Inheritance: 1 point Individuals in the following pedigree that are half shaded can be classified as: Carriers

  13. Complex Inheritance: 2 points The process by which plants are bred to produce larger fruits is called: Selective Breeding

  14. Complex Inheritance: 3 points A cross between a blue monster (BB) and a green monster (GG) produces all mixed blue-green offspring. This type of inheritance is known as: Co-Dominance

  15. Complex Inheritance: 4 points Most sex-linked genes are located on what chromosome? X Chromosome

  16. Complex Inheritance: 5 points Colorblindness is more common in males than in females because… The allele for colorblindness is recessive and located on the X chromosome

  17. Practice Problems: 1 point If a female rabbit heterozygous for red eyes (XR Xr) is crossed with a white-eyed male (XrY), what percent of their offspring would have white eyes? 50%

  18. Practice Problems: 2 points T t Tall (T) is dominant to short (t). What are the possible genotypes for offspring in the punnett square? TT, Tt, tt T t

  19. Practice Problems: 3 points Two Roan Cows (RW and RW) are mated. These cows show codominant inheritance. What percent chance will their offspring be red? White? Roan? 25% Red, 25% White and 50% Roan

  20. Practice Problems: 4 points A man heterozygous for blood type A marries a woman heterozygous for blood type B. What is the chance their first child will have type AB blood? 25%

  21. Practice Problems: 5 points Huntington’s disease is a dominant disorder. What is the chance that individual A will be afflicted with the disorder? 50% ?

  22. Misc.: 1 point AN individual would have at least ______ dominant allele(s) if the dominant phenotype is expressed. One

  23. Misc.: 2 points In a test cross, if one parent’s genotype is homozygous dominant, how many of the offspring will have the dominant phenotype? All of the offspring.

  24. Misc.: 3 points A cross between a black rat (BB) and a white rat (bb) produces all gray haired offspring. What type of inheritance is this? Incomplete Dominance

  25. Misc.: 4 points The disorder that results in an extra chromosomes on number 21 in a karyotype. Down Syndrome

  26. Misc.: 5 points What is the percent chance that a human offspring will be male? 50%

  27. Daily Double! As a team, decide how many of the points you already have you wish to wager. If you get the question correct, you will earn double the points you wagered.If you get the question incorrect, you will lose the points you wagered. Good luck!
