2. $100 Jeopardy Menu The Work of Gregor Mendel This principle states that some alleles (forms of a gene) are dominant, while others are recessive. Mendel made these conclusions based on his studies with pea plants. What is the principle of dominance?

3. $200 When Gregor Mendel crossed tall (TT) plants with short (tt) plants, the short phenotype (trait) did not reappear until this generation. Jeopardy Menu The Work of Gregor Mendel What is the F2 generation?

4. $300 During gamete (sperm and egg) formation, alleles do this; as a result, gametes only carry a single copy of each gene. Jeopardy Menu The Work of Gregor Mendel What is segregate?

5. $400 Beyond Gregor Mendel: Four o’clock flowers show incomplete dominance. For example, a cross between a red (RR) flower and a white (WW) flower, all offspring are pink (RW). If two pink flowers are crossed, this percentage of offspring would be expected to be pink. Jeopardy Menu The Work of Gregor Mendel Question: What is 50%

6. $500 A cross of a black chicken (BB) with a white chicken (WW) produces all speckled offspring (BW) containing BOTH black and white feathers. This is an example of this type of inheritance pattern. Jeopardy Menu The Work of Gregor Mendel Question: What is codominance?

7. $100 In pea plants, round seeds (R) are dominant to wrinkled seeds (r). Two heterozygous plants are crossed. What percentage of offspring will be round? What is 75% Jeopardy Menu Probability & Punnett Squares

8. $200 If a couple has three sons, this is the probability that their next child will be a daughter. Jeopardy Menu Probability & Punnett Squares What is 50% (1/2)?

9. $300 A homozygous tall plant is crossed with a short plant. What percentage of offspring will be tall? What is 100%? Jeopardy Menu Probability & Punnett Squares

10. $400 A round-seeded plant is crossed with a wrinkled-seeded plant. Approximately 500 out of the 1000 offspring produced have wrinkled seeds. This is the most likely genotype of the round-seeded plant. What is Rr (heterozygous)? Jeopardy Menu Probability & Punnett Squares

11. $500 In fruit flies, R eyes (R), are dominant over white eyes (r). In a cross between two red-eyed fruit flies, approximately 25% of offspring had white eyes. These were the most likely genotypes of the parents. What are Rr and Rr? Bonus $100: What is the special name for this kind of cross? Monohybrid Cross Jeopardy Menu Probability & Punnett Squares

13. $200 This process results in the production of 4 genetically different daughter cells. Jeopardy Menu Meiosis and Mitosis What is meiosis?

14. $300 In Drosophila (fruit flies), male gametes (sperm cells) contain 4 chromosomes. This means that a body cell in a fruit fly must contain this number of chromosomes. Jeopardy Menu Meiosis and Mitosis What are 8 chromosomes?

15. $400 Gametes (sperm and eggs) are produced by this process. What is meiosis? Jeopardy Menu Meiosis and Mitosis

16. $500 During Prophase I of meiosis, these pairs of chromosomes form tetrads (groups of four). What are homologous chromosomes? Jeopardy Menu Meiosis and Mitosis

17. $100 These types of chromosomes are not different in males and females; there are 44 of them in human cells. Jeopardy Menu Human Chromo - somes What are autosomes?

18. $200 Each human egg cell contains this number of X chromosomes. Jeopardy Menu Human Chromo - somes What is 1?

23. $100 Jeopardy Menu DNA, RNA, and proteins James Watson and Francis Crick discovered that DNA has this structure, resembling a twisted ladder. What is a double helix?

24. $200 This nucleic acid, which is usually single- stranded, contains the sugar ribose, phosphates, and four nitrogenous bases (adenine, guanine, cytosine, and uracil). Jeopardy Menu DNA, RNA, and proteins What is RNA?

25. $300 During this process the DNA strands separate and one DNA strand is used to make mRNA, and during this process mRNA is used to produce proteins. Jeopardy Menu DNA, RNA, and proteins What are transcription and translation?

26. $400 Proteins are composed of these smaller subunits. Jeopardy Menu DNA, RNA, and proteins What are amino acids?

27. $500 If a gene has the DNA sequence TACGGATAT, this will be the amino acid sequence of the protein produced. (Hint: use the genetic code on p.303). Jeopardy Menu DNA, RNA, and proteins What is protein with the sequence methionine – proline – isoleucine ?
