Fish Clonal Hybrid Exome Sequences and Fitness Traits Across 300,000 Years

Jan Ko from the University of Ostrava published an open-access dataset analyzing the exome sequences and fitness-related phenotypic traits of sexually-reproducing fish species and their clonal hybrids. The dataset includes clones with evolutionary ages ranging from F1 generations to 300,000 years. It was used to test hypotheses about mutation accumulation and fitness degradation in asexual lineages.

Use Cases

• Test the Muller's ratchet hypothesis based on time-dependent mutation accumulation data.
• Analyze the non-synonymity and radicality of amino-acid substitutions in clonal genomes.
• Compare fitness-related phenotypic traits between sexual and asexual fish lineages.
• Model the efficiency of purifying selection in non-recombining genomes over evolutionary time.

Strengths

• Includes clones spanning a wide evolutionary age range up to 300,000 years.
• Combines exome sequence data with fitness-related phenotypic trait measurements.
• Data directly addresses a long-standing evolutionary biology hypothesis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness is unverified as the last update date is unknown.
