Incomplete Dominance and Codominance So far, we have been studying the inheritance of genes that show complete dominance. In other words, one allele is completely dominant over another. In some cases, such as incomplete dominance and codominance, one allele is not completely dominant over another or the alleles affect the phenotype equally. Examples of incomplete dominance include feather color in parrots (C*Cf = blue, C'C = yellow, C*Cf = green) and hair texture in humans CC = %3D curly; C'C' = straight; CC' = wavy %D Practice Problem 3: 3a. If a straight-haired man marries a curly haired woman, what are the predicted genotypes and phenotypes of their children?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
