alleryStart learning →A trait is best described as which of the following?
AA chromosome that carries many linked genes
BA gamete that carries one allele of one gene
CA cross between two true-breeding parents
DA variation in a heritable characteristic
Answer & Solution
Correct answer: D. A variation in a heritable characteristic
1. A characteristic is the feature being followed, such as flower colour.
2. A trait is a variation in the physical appearance of that heritable characteristic, such as violet or white.
3. Chromosomes and gametes are physical structures, not variations in appearance.
4. A cross is a procedure, so it cannot be a trait.
