The Hungarian Grey cattle breed, nearly extinct after WW2, shows high genetic diversity and a pure taurine origin. Its unique genetic background is preserved, distinguishing it from other Podolian cattle.
Area of Science:
- Animal Genomics
- Conservation Genetics
- Evolutionary Biology
Background:
- The Hungarian Grey (HG) cattle breed faced near extinction post-WW2, with limited surviving individuals.
- Previous genetic studies lacked comprehensive, representative sampling for accurate diversity and evolutionary assessments.
- Understanding HG cattle's genetic status is crucial for conservation and breed history.
Purpose of the Study:
- To conduct a comprehensive genomic analysis of the Hungarian Grey cattle breed.
- To investigate the breed's phylogenetic placement and evolutionary history using a representative sample.
- To assess the genetic diversity and conservation status of the Hungarian Grey cattle.
Main Methods:
- Mitochondrial DNA (mtDNA) sequence variation analysis.
- Phylogenetic analysis of 110 founder individuals.
- Haplotype diversity and genetic similarity assessments.
Main Results:
- All identified haplogroups belong to the taurine T macro-haplogroup, predominantly T3 (89.1%).
- Phylogenetic analysis confirmed a purely taurine origin, with no ancient European aurochs haplogroups.
- High haplotype diversity (Hd = 0.94) and genetic similarity to Podolian breeds, especially Maremmana cattle, were observed.
Conclusions:
- The Hungarian Grey cattle breed possesses a preserved genetic background and high diversity.
- The breed exhibits a purely taurine origin, distinct from ancient European aurochs.
- Selective breeding and limited crossbreeding maintained the HG breed's original beef production purpose.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
