    A Law of segregation Correct Answer Incorrect Answer
    B hybrid cross Correct Answer Incorrect Answer
    C Law of purity Correct Answer Incorrect Answer
    D Law of dominance Correct Answer Incorrect Answer

    Solution

    In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.

    Key Points

    • Dominant alleles are expressed exclusively in a heterozygote, while recessive traits are expressed only if the organism is homozygous for the recessive allele.

    • A single allele may be dominant over one allele, but recessive to another.
