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

3 2 heterozygous dominant plants are crossed.

4 2 heterozygous dominant plants are crossed
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

5 Add to table of contents:
MORE PUNNETT SQUARES pg 48 COMPLEX INHERITANCE pg 49

6 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

7 Know your colors?

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

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

23 Heterochromia – amount of melanin in the eyes

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

26 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?

27 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?

29 A dark purple flower is crossed with a white flower
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?

30 A dark purple flower is crossed with a white flower
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?
