Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominant over the other. one example of codominance is blood type in humans; the alleles for type a blood and type b blood are codominant. if a man who is homozygous for type a blood and a woman who is homozygous for type b blood have children, what would you expect to find in the children?

half will have type a and half will have type b blood.
the children will all have type b blood.
the children will all have type ab blood.
the children will all have type a blood.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
