Match each inheritance pattern with the correct example.

1. a red flower and a white flower creates a pink flower
incomplete dominance
2. two equally dominant genes create type ab blood
sex-linked gene
3. a female carries the gene for color blindness on only one x chromosome
codominance
4. a dog with a genotype of cc has the same phenotype as a dog with a genotype of cc
complete dominance

4. multiple crosses were made between true-breeding lines of black and yellow labrador retrievers. all the f1 progeny were black. when these progeny were intercrossed, they produced an f2 consisting of 91 black, 39 yellow and 30 chocolate. a. propose an explanation for the inheritance of coat color in labradors. b. propose a biochemical pathway for coat color determination and indicate how the relevant genes control coat coloration.
