Exploring Genetics: Mendel, Heredity & Punnett Squares

Dive into the world of genetics with topics ranging from Mendel's experiments to Punnett Squares, learning about heredity and flower power along the way. Discover the foundations of genetic inheritance and explore how traits are passed down through generations. Uncover the significance of dominant and recessive traits, as well as the fascinating process of genetic cross-pollination in plants. Gain insights into the role of chromosomes and genes in determining genetic traits. Get ready to unravel the mysteries of genetics in this stimulating journey through the principles of heredity.

  2. What step did Mendel take to make sure his pea plants cross pollinated? He removed the anthers. 1 - $100

  3. 1 - $200 • What did Mendel realize was the result of his experiments with pea plants? • Each trait had two sets of instructions, one from each parent.

  4. 1 - $300 • What did Mendel discover about recessive traits? • Recessive traits reappear in the second generation.

  5. 1 - $400 • What is Mendel’s ratio for dominant to recessive traits? • 3 to 1

  6. 1 - $500 • Who was Gregor Mendel. • An Austrian monk that studied traits in pea plants and came up with the foundations of Heredity.

  7. 2 - $100 • A plant with two dominant OR two recessive alleles is said to be? • Homozygous

  8. 2 - $200 • What happens when a plant self pollinates? • All of its offspring will have the same traits as the parent. (EXAMPLE: Gizmos Alien Inheritance – Asexual Reproduction)

  9. 2 - $300 • When a plant fertilizes itself, it is called? • Self-pollinating plant

  10. 2 - $400 • What kind of plant produces offspring with the same traits as the parent? • DOUBLE JEOPARDY • True-breeding

  11. 2 - $500 • What is a plant that has two dominant or two recessive genes called? • Homozygous

  12. 3 - $100 • What is the table that shows what the cross of both parents looks like? • A Punnett Square

  13. 3 - $200 • If purple (P) is dominant, and white (p) is recessive, what color will one out of every four of the offspring be? • DOUBLE JEOPARDY • White

  14. 3 - $300 • If you cross P with a p, what will the offspring be? • Pp

  15. 3 - $400 • If the offspring are: PP, Pp, Pp, pp, what is the percentage of pp? • 25%

  16. 3 - $500 • What is used to organize possible offspring combinations? • A Punnett Square

  17. 4 - $100 • What are homologous chromosomes? • Chromosomes that carry the same set of genes.

  18. 4 - $200 • What describes the way cells divide in asexual reproduction? • Mitosis

  19. 4 - $300 • What are chromosomes that carry the same sets of genes called? • Homologous chromosomes

  20. 4 - $400 • What do you call one set of instructions for an inherited trait? • Genes

  21. 4 - $500 • Walter Sutton discovered that genes are located on ____________________. • Chromosomes

  22. 5 - $100 • Why do sex-linked disorders occur more often in males? • Males have only one X chromosome.

  23. 5 - $200 • What carries the gene that determines sex? • Sex chromosome

  24. 5 - $300 • What are two forms of a gene, one from each parent, called? • Alleles

  25. 5 - $400 • Offspring that are different from both parents are produced by_________________? • Sexual Reproduction

  26. 5 - $500 • What is it called when cells are copied with half the number of chromosomes? • Meiosis

  27. Final Jeopardy • What is incomplete dominance? • Each allele has its own degree of influence
