Complex Patterns of Inheritance Incomplete/Codominance So far, we have learned about simple Mendelian inheritance--traits controlled by dominant and recessive paired alleles However, MOST alleles are not simply dominant or recessive
Incomplete Dominance Incomplete Dominance = The phenotype of the heterozygote is intermediate between those of the two homozygotes Example: Snapdragons RR = Red Example: Snapdragons
RR = Red WW= White Example: Snapdragons RR = Red WW= White RW = Pink Example: Hair
CC = Curly SS = Straight CS= Wavy Punnett square problem: 2 Wavy haired people have a child C C S S
Example: Hair CC = Curly SS = Straight CS= Wavy Punnett square problem: 2 Wavy haired people marry C C S
CC CS S CS SS
25% Curly 50% Wavy 25% Straight Practice Problem: Incomplete Dominance For each practice problem, draw the Punnett square and give the phenotype ratios A: Cross a pink snapdragon with a white
snapdragon B: Cross a red snapdragon with a white snapdragon Codominance Codominance = the heterozygote produces the phenotypes of BOTH homozygotes Example: Blood Type
Example: Chickens BB = Black WW = White BW = Checkered Other examples Cows: RR = Red
WW= White RW=Roan (red and white spots) Horses: GG = Gray WW = White GW=Apaloosa (white with gray spots) Example: Horses Punnett square problem: 2 appaloosa horses
are crossed G G W W Example: Horses
Punnett square problem: 2 appaloosa horses are crossed G G W GG GW
W GW WW 25% Gray 50% Appaloosa 25% White
Codominance Practice Problem For each practice problem, draw the Punnett square and give the phenotype ratios A. Cross a checkered chicken with a black chicken B. Cross two checkered chickens together Output Activity
