P-M status of 13 isofemale lines from a natural population of Drosophila melanogaster from Biisk (Altai) was determined by estimation of frequency of female gonadal sterility in diagnostic crosses. Content of P-elements in genomes was estimated by in situ hybridization. The average level of P-sensitivity was 97.3%; the average number of P-element copies per genome was 27.5. This value is significantly higher than estimates of average copy number of the P-element obtained for other populations with similar levels of P-sensitivity. No relationship between P-element copy number in the lines and level of their P-sensitivity was demonstrated. Based on the data obtained, the Altai population may be assigned to populations of M'-type.
