Kind: research · Impact: low

## In brief

- A study examined genotype-specific polyphenism in pea aphids.
- The polyphenism is associated with reproductive trade-offs.
- The aphids show distinct gene expression patterns but limited DNA methylation differences.

## Why it matters

The study links a genotype-dependent trait in pea aphids to reproductive trade-offs, which helps clarify how one genotype can produce different phenotypes. It also suggests DNA methylation contributes little to these differences compared with gene expression.
