A family of repetitive DNA sequences in the genome of the sawfly, Strongylogaster osmundae (Hymenoptera: Tenthredinidae) was characterized. The family consists of a tandemly arranged array whose basic repeat unit is 1.0 kb. According to the compositions and arrangements of bases, the basic repeat unit can be divided into three distinct domains. Three domains share nucleotide sequence homology of 88, 74 and 89%, respectively, between members in this family. Second domain which had lower homology with the other two domains was found characteristically rich with polypurine/polypyrimidine sequences.

Electrophoretic variations of prophenoloxidase were obtained from natural populations of Drosophila melanogaster. A1, one of the 2 isoforms of the prophenoloxidases, is polymorphic: 10 fast-migrating and 2 slow-migrating types were found in polyacrylamide gel electrophoresis among 271 wild strains. The majority were the intermediate-migrating type. By use of these variants, A1 gene was mapped at 79.6 on the right arm of the second chromosome. By deletion mapping, its cytological position was located at 55A-B. In the electropherograms, hybrids between the types differing in mobility exhibited 3 bands, indicating that A1 is a dimeric protein. The gene for A1 is expressed through larval, pupal and adult stages.

Statistical methods for estimating the branching order and the branching dates from DNA sequence data, taking into account of the rate variation among lineages, are reviewed. An application of the methods to data from primates suggests that chimpanzee is the closest relative of man, and further suggests that these two species diverged about 4-5 million years ago.
