Presentation Transcript

  1. Review: 2 heterozygous dominant plants are crossed. Complete the punnett square: • Green is dominant, white is recessive

  2. 2 heterozygous dominant plants are crossed. G g G g

  3. 2 heterozygous dominant plants are crossed. Complete the % and genotype & phenotypes. Green is dominant, white is recessive • 1. What percent would be homozygous green? • 2. What percent would be heterozygous green? • 3. What percent would be white? G g GG Gg G g Gg gg

  4. Add to table of contents: • MORE PUNNETT SQUARES pg 48 • COMPLEX INHERITANCE pg 49

  5. Complex Inheritance pg 49 • -Incomplete dominance -a condition in which the trait is neither dominant nor recessive, so genes blend together. red (CRCR) flower X white (CWCW) flower = all pink (CRCW) flowers. OR Red(RR) flower X white (WW) flower = all pink(RW) flowers

  6. Know your colors?

  7. Draw the punnett square and fill in. CR CR CW CRCW CRCW CW CRCW CRCW

  8. Codominance-a condition where both genes are equally dominant, so both genes show up. • Black chicken(BB) X a white(WW) = checkered chicken(BW).

  9. Draw the punnett square and fill in. B B BW BW W W BW BW

  10. Incomplete or Co- dominance?

  11. Incomplete or Co- dominance?

  12. Incomplete or Co- dominance?

  13. Incomplete or Co- dominance?

  14. Incomplete or Co- dominance?

  15. Incomplete or Co- dominance?

  16. Incomplete or Co- dominance?

  17. Heterochromia – amount of melanin in the eyes

  18. Do the following sample complex inheritance punnett squares on pg. 48:

  19. A homozygous white bull is crossed with a homozygous brown cow. B=brown W=white Codominance What are the genotypes and phenotypes of the offspring?

  20. A homozygous white bull is crossed with a homozygous brown cow. B=brown W=white Codominance W W B B What are the genotypes and phenotypes of the offspring?

  21. A dark purple flower is crossed with a white flower. The traits are incompletely dominant. P=dark purple W=white What are the genotypes and phenotypes of the offspring?

  22. A dark purple flower is crossed with a white flower. The traits are incompletely dominant. P=dark purple W=white P P W W What are the genotypes and phenotypes of the offspring?

  23. Answer Essential Question
