Transmission of DNA methylation: genetic or epigenetic ? A transgenerational case study in quails

Key Points

• DNA methylation patterns reveal significant transgenerational effects in quails, indicating epigenetic influence.
• Evidence shows that environmental factors may alter DNA methylation across generations in quails.
• Transgenerational study analyzed the impact of phenotypic changes linked to DNA methylation in quails.
• Findings highlight the need for more comprehensive studies to unravel genetic versus epigenetic inheritance mechanisms.
