Quizplus · Accepted Answer

When a child receives different forms of a certain gene from his/her parents, he or she is said to be heterozygous. This means that the child has two different versions (or alleles) of the same gene - one from the mother and one from the father. Dominant refers to a trait that is expressed when present, while a phenotype is the physical or visible expression of a trait. Homozygous refers to having two identical alleles for a gene. None of these options is the best choice when a child receives different forms of a certain gene from his/her parents.
