B. Increased exposure to UV light increases the risk of mutation occurring.
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.
Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.
