Types of Genetic Problems   1. monohybrid cross - a genetic cross that tracks a single trait.   2. testcross - an individual with an unknown genotype for a particular trait is crossed  with a homozygous recessive individual   3. dihybrid cross - a genetic cross that tracks two traits.   4. incomplete dominance - a situation where two different alleles occurring in a pair are  both expressed to some degree. This results in offspring that have intermediate  phenotypes compared to the parents. For instance, a red flower crossed with a white  flower produces pink-flowered offspring.   5. codominant - a situation where two different alleles occurring in a pair are both  expressed. This results in both traits appearing in the offspring. For instance, with  human blood groups an AB genotype will result in the presence of both the "A" protein  and the "B" protein appearing on the red blood cell membrane.
