Is a carrier homozygous or heterozygous?

Answer 1

No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).

Answer 2

A carrier would have to by heterozygous. Carriers don't express the "carried" allele but have it nevertheless. This means it has to have one allele of each. For example, if a trait has alleles A (dominant) and a (recessive), the heterozygous genotype will be Aa and will display the dominant phenotype (unless the trait is a special/more complex type of expression like incomplete dominance).

Answer 3

The term carrier in a heterozygous individual refers to the fact that the unexpressed characteristic can still be passed to 50% of any produced offspring thus the trait can be carried forward to the next generation, even if the trait remains unexpressed for more than one generation.

Answer 4

Yes, it is true that a carrier is always a heterozygous individual.

Answer 5

No. They have one allele and it is 'hidden' in their genetic make up by a dominate allele.
