Aim. To study the genetic structure of Ukrainian Large White pigs using mitochondrial DNA-markers. Methods. Multiplex PCR-AFLP analysis, remarkable for the investigation of D-loop fragment between posi- tions 15531 and 15959 of the pig mitochondrial genome with one monomorphic 15558W and fi ve polymorphic sites TasI 15580T > C, 15616T > C, 15714T > C, 15758T > C, 15916A > T, was used. The presence or absence of site TasI in the abovementioned positions determines mitochondrial DNA haplotypes, indicated with Latin letters from A to P. Results. Seven mitochondrial DNA haplotypes of different frequency were revealed among Ukrainian Large White pigs. The highest frequency was noted for haplotypes G (0.141), J1 (0.133) and N (0.591), previously described for wild pigs of Belgium, France, Italy (G); wild pigs of Japan and China, Meis- han and Large White breeds (J1) and wild pigs of Japan and China, Berkshire and Large White breeds (N). The frequency for haplotype L (Belgian wild pig and Large White) is 0.022; haplotype A (French wild boar, Mangalica, Duroc) − 0.003; haplotype C (wild pig of France, Belgium, Poland, Israel and Landrace, Welsh breeds) − 0.092. Haplotype B1 (0.019) was revealed in Myrgorod breed, Poltava Meat and Red White Belted breeds, bred on its basis. Conclusions. The haplogroup of mitochondrial DNA of Ukrainian Large White pigs includes seven haplotypes of mitochondrial DNA. Pigs with haplotypes G, J1, N and L may be referred to rep- resentatives of Ukrainian Large White pigs, which did not have introgression of maternal line of other breeds.

Mutualisms are balanced antagonistic interactions where both species gain a net benefit. Because mutualisms generate resources, they can be exploited by individuals that reap the benefits of the interaction without paying any cost. The presence of such ‘cheaters’ may have important consequences, yet we are only beginning to understand how cheaters evolve from mutualists and how their evolution may be curtailed within mutualistic lineages. The yucca–yucca moth pollination mutualism is an excellent model in this context as there have been two origins of cheating from within the yucca moth lineage. We used nuclear and mitochondrial DNA markers to examine genetic structure in a moth population where a cheater species is parapatric with a resident pollinator. The results revealed extensive hybridization between pollinators and cheaters. Hybrids were genetically intermediate to parental populations, even though all individuals in this population had a pollinator phenotype. The results suggest that mutualisms can be stable in the face of introgression of cheater genes and that the ability of cheaters to invade a given mutualism may be more limited than previously appreciated.
