Question: 1 / 400

If an organism is homozygous for a trait, what does this mean?

It has two copies of the same allele

A homozygous organism means that it has two identical alleles for a specific trait. This is caused when the individual inherits the same allele from both parents. In this case, both alleles will have the same effect on the trait, leading to a consistent expression of the trait. The incorrect options are B) and D) because they both describe a state of heterozygosity, where the organism has two different alleles for a specific trait. Option C) is incorrect because being a carrier of a genetic disorder is not related to being homozygous for a trait.
