Genotype specific polyphenism in pea aphids is associated with reproductive trade-offs, distinct gene expression patterns and limited DNA methylation differences
Nature ·
The 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.
