Solution
Understanding the Concept of a Carrier
-
Definition of a Carrier: A carrier in genetics is an individual who carries one copy of a recessive allele that does not manifest in their phenotype but can be passed on to their offspring.
-
Genetic Terminology:
- Homozygous: This refers to having two identical alleles for a particular gene (e.g., AA or aa).
- Heterozygous: This refers to having two different alleles for a particular gene (e.g., Aa).
- Hemizygous: This typically refers to having only one allele for a gene in an otherwise diploid organism, often seen in males with X-linked genes (e.g., XY).
Answer Selection
Based on the definition of a carrier, the appropriate choice must indicate that the individual has one dominant and one recessive allele.
Final Answer
A carrier is always heterozygous.
