The difference between codominance and incomplete dominance?
Incomplete dominance is the mixing of the two alleles (for example, red+white=pink) and codominance is the two alleles are each shown.

In corn, yellow kernel color is governed by a dominant allele; white, by its recessive allele. A random sample of 1,000 kernels from a population that is in equilibrium reveals that 910 are yellow and 90 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of heterozygous in this population?

Over the summer, 20 friends (lets say 10 males and 10 females) charter a plane to go on a round-the-world tour. Unfortunately, they all crash land (safely) on a deserted island. No one finds them and they start a new population totally isolated from the rest of the world. Two of the friends carry (i.e. are heterozygous for) the recessive cystic fibrosis allele (c). Assuming that the frequency of this allele does not change as the population grows, what will be the incidence of cystic fibrosis on this island?
What is 0.25%?
