A type of inheritance in which the phenotypes of the heterozygote and dominant homozygote are the same.

a) codominance
b) incomplete dominance
c) complete dominance
d) multiple alleles

Complete Dominance.

Explanation:

This is a rare form of dominance where the heterozygous condition wherein the allele that is regarded as dominantly complete; masking the reactions of the allele that is recessive. Say an individual possessing two alleles that are both dominant, the trait that they represent will be expressed. But if the individual has two alleles in such a way that one is dominant and the other one is recessive, the dominant allele will be expressed while the recessive allele will be suppressed. Hence, the heterozygote will carry the same phenotype as that of the dominant homozygote.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
