<span>The secretion of excess mucous in the digestive tract may result in loose stools or diarrhea. The purpose of the excess secretions is to lubricate the digestive tract so that food can pass through during digestion with greater ease. The secretion of excess mucous in the respiratory passageway could result in increased coughing as the body attempts to expel the mucous (and the offending irritants) from the lungs and bronchial tubes. This occurs when either physical debris (such as inhaled dust or dirt particles) or pathogens (such as bacteria and viruses) have entered the respiratory passageway and the body attempts to remove them; an example is the common cold.</span>

E is a dominant allele for wet earwax and e is a recessive allele for dry earwax. if two individuals with the phenotype of wet e
MrRissso [65]
Given 
E dominant allele for wet
e recessive allele for dry

that means
for phenotype wet, the possible genotypes are EE, or Ee, and
for phenotype dry, the only possible genotype is ee.

Therefore we also know that the child who has dry earwax has genotype ee.
Since the child inherits one allele from each parent, therefore each parent must have a recessive allele "e".

If both parents have phenotype wet earwax, they both must be heterozygous for wet/dry earwax, namely Ee.
