What does negative allometry describe in terms of trait size relationships?

Negative allometry describes a specific relationship in which one trait grows at a slower rate compared to another trait as an organism increases in size. In essence, this means that while one trait may become larger, the other trait's growth is relatively reduced when considering their sizes. This relative reduction can be observed in various biological contexts, such as in the relationship between body size and the size of appendages, where, for example, the limbs become proportionally smaller compared to the overall body size as the organism grows. Therefore, the answer correctly captures the concept of negative allometry by highlighting a reduction in the size of one trait in comparison to another during growth.
