Ethiopian Crossbred Dairy Cattle Haemoglobin Polymorphism and F-Statistics

117 crossbred lactating cows from three Ethiopian milksheds were analyzed for haemoglobin allele frequencies. The study found substantial inbreeding within subpopulations, with an inbreeding coefficient (FIS) of 0.41 for location-based groups. Eyerusalem Tesfaye published this dataset on figshare in March 2026, revealing reduced genetic diversity in the tested population.

Use Cases

• Calculate fixation indices (FIS, FST) based on reported allele and genotype frequencies.
• Assess Hardy-Weinberg equilibrium in crossbred cattle populations based on the reported chi-square test result.
• Analyze the relationship between genetic heterozygosity and bloodline percentage (e.g., 50% vs 87.5% Holstein Friesian) based on the reported heterozygosity range.
• Compare genetic differentiation among subpopulations based on the reported FST values for blood level (0.06) and location (0.01).

Strengths

• Includes specific genetic metrics: allelic frequencies (0.89 for HbA, 0.11 for HbB) and genotype frequencies (0.84, 0.11, 0.05).
• Reports calculated inbreeding coefficients (FIS of 0.38 and 0.41) and genetic differentiation values (FST of 0.06 and 0.01).
• Sample size of 117 animals is clearly stated, with a breakdown of 39 cows per location and 13 per blood level.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the three studied Ethiopian milksheds.
