摘要
The character of TRD (transmission ratio distortion) was analyzed using the database formed on the basis of the results obtained for a collection of mice carrying different t haplotypes during 30 years of experimental observations. Quantitative TRD parameters were determined in male mice with T/t(w) genotypes from natural populations in crosses with females from laboratory collections. The TRD value varied in the range from 0.41 to 0.74. The frequencies of t haplotypes in natural Mus musculus populations from different regions (Moscow, Moscow oblast, Tajikistan, Lithuania, and Mongolia) varied from 12% (Tigrovaya Balka, Tajikistan) to 44% (Ulan-Bator, Mongolia). The factors and mechanisms determining a low frequency of t haplotypes in natural populations are discussed.
