  "summary": "Genetic analysis in zebrafish relies heavily on invasive, labour-intensive molecular genotyping. This limits throughput and phenotypic analysis, particularly for homozygous mutants that lack readily detectable phenotypes at early developmental stages. To overcome these limitations, we adapted CRISPR-mediated knock-in strategies to insert complete secondary marker cassettes (including promoter,…",
