Complementation for viability of the compounds tx/ty in complete lethal haplotypes t6, t12, tw5, tw12, tw18, tw73, twPa-1 belonging to the seven basic complementation groups was studied. In the overwhelming majority of crosses a lack of tx/ty offspring was revealed but there is also evidence of non-complete complementation of the tx/ty haplotypes, except for T/tw73XT/tw12, T/tw18XT/t12, T/tw73XT/tw18 crosses in which the level of complementation for viability exceeds 100%. The maternal effect for compound variability was significantly revealed in 9 out of the 19 matings. In addition, reciprocal matings of heterozygotes T/txXT/ty were tested for fertility. In two cases, the maternal effect was also revealed for this character. Comparison of data on viability of the compounds and the fertility of the original strains gives grounds to believe that the tx/ty haplotypes are not completely recessive and partially manifest themselves in the heterozygotes, decreasing fertility in a number of matings. In some cases, these t-haplotypes yield an effect, close to negative complementation, which may be associated with the interaction of the proteins of t-haplotypes.
研究了属于七个基本互补群的完全致死单倍型t6、t12、tw5、tw12、tw18、tw73、twPa-1中化合物tx/ty的生存力互补情况。在绝大多数杂交中，未发现tx/ty后代，但也有证据表明tx/ty单倍型存在不完全互补，除了T/tw73×T/tw12、T/tw18×T/t12、T/tw73×T/tw18杂交，其生存力互补水平超过100%。在19次交配中的9次中，显著发现了化合物变异性的母体效应。此外，对杂合子T/tx×T/ty的正反交进行了育性测试。在两个案例中，该性状也发现了母体效应。比较化合物生存力数据和原始菌株的育性数据有理由相信，tx/ty单倍型并非完全隐性，在杂合子中部分表现出来，在一些交配中降低了育性。在某些情况下，这些t-单倍型产生的效应接近负互补，这可能与t-单倍型蛋白质的相互作用有关。
