    Notes: Abstract Paternity assessment through DNA fingerprinting by synthetic oligonucleotide probes was applied to one birth cohort in a social group of free-ranging rhesus macaques (Macaca mulatta) on Cayo Santiago. The 11 group males and 9 males from other groups were observed mating with the females. Paternity was determined for 11 of the 15 infants. Male dominance rank was not associated with reproductive success. High-ranking resident males (N=5) sired 27% of the infants born during a one-year study. Four of the 11 infants of known paternity were sired by males of other social groups. The four infants of unknown paternity were sired either by males not observed mating with the females or the low-ranking male who was not fingerprinted. Male dominance rank was not associated with reproductive activity during conception cycles. These results suggest that the effect of rank on male reproductive success is not a predictable correlation, but a conditional probability.

    Notes: We screened a total of 100 unrelated patients with neurofibromatosis type 1 (NF1) for mutations in exons 5 and 8 of the NF1 gene using temperature gradient gel electrophoresis (TGGE). Careful interpretation of exon 5 TGGE patterns was necessary due to interference by an exonic polymorphism. Three novel mutations were identified: a stop mutation in exon 5 (Q239X) caused by a C→T transition at cDNA nucleotide position 715, a transition at the invariant G of the splice accceptor site in intron 4c (G655-1A), and a transversion at the invariant G of the splice donor site in intron 8 (G1185+1T). Analysis of mRNA revealed the predicted abnormal splice products. While skipping of exon 5 causes a shift in the reading frame with a premature stop codon downstream in the middle of exon 6, skipping of exon 8 leads to an in-frame deletion with the predicted protein product being shortened by 41 amino acids.

    Notes: The fundamental framework for uncovering factors affecting the evolution of social behavior rests upon analyses of variation in reproductive success. In species where females mate with multiple males, paternity is invisible in the absence of genetic data. We determined paternity in two populations of rhesus macaques, Macaca mulatta, using both single locus and multilocus techniques. One troop, Group R, is one of four troops living on a 15 ha island (Cayo Santiago) off the coast of Puerto Rico, while the other troop, Group M, was translocated from Cayo Santiago to the Sabana Seca Field Station (Puerto Rico) in 1984. About a dozen human-derived short tandem repeat (STR) markers have been found to be polymorphic in the study of populations and provide the initial paternity determination. Final evaluation of paternity is then confirmed by multilocus DNA fingerprinting using synthetic oligonucleotide probes. Body condition, age, and dominance rank have an impact on male progeny production, while canine size does not. We suggest that nonagonistic competition in the form of sperm competition and endurance rivalry will modulate male reproductive success. A large body size among males provides them with an advantage in both sperm competition and endurance rivalry. Comparison of the two populations indicated that demographic, social, ecological, and morphological factors interact to regulate variation in reproductive success among male nonhuman primates.

    Bipolar clamping improves the sensitivity of mutation detection by temperature gradient gel electrophoresis (1998)

    Notes: Temperature gradient gel electrophoresis (TGGE) is a rapid and sensitive screening method for point mutations and other small DNA alterations. Usually a polymerase chain reaction (PCR)-product of 150 to 500 bp that has been clamped at one end by a psoralen molecule or a “GC-clamp” is tested for abnormal melting characteristics by electrophoresis in a temperature gradient. Under optimal conditions, a heterozygous mutation within the fragment is detected through the presence of three additional bands in the TGGE gel, the mutant homoduplex and two heteroduplex bands. However, the ideal pattern of four sharp bands is not always found due to inconsistencies in melting behavior along the sequence of the DNA fragment under study. Some of these fragments show fuzzy bands that may impede or even prevent the detection of a mutation. Here, we describe a method to overcome this problem by utilizing one psoralen clamp at each end of the PCR product. Using TGGE assays established for exons 16, 17, and 18 of the NF1 gene and for exon 14 of the FBN1 gene as examples, we show that bipolar clamping may transform blurred bands into sharp ones and may visualize mutations that could not be detected by conventional single-sided clamping.

    Increased microsatellite variability in Macaca mulatta compared to humans due to a large scale deletion/insertion event during primate evolution (1995)

    Notes: Human (GATA)n microsatellites D12S66 and D12S67 could be successfully amplified by polymerase chain reaction (PCR) in various species of apes and monkeys. In 86 unrelated animals of the most intensively studied species Macaca mulatta we demonstrated five alleles at “D12S66” differing in size in increments of 4 bp (159-175 bp), whereas 17 alleles were observed at locus “D12S67”. The alleles of the latter locus are distributed in two separate groups with no alleles of intermediate size. Six alleles were found between 108-128 bp and 11 alleles between 181-249 bp. Mendelian inheritance of the codom-inant alleles was proven by family studies. Sequencing of the “D12S67” locus revealed that the shorter alleles are characterized by a single perfect (GATA)n stretch whereas the longer alleles consist of two blocks of (GATA)n repeats separated by an intervening sequence of 9 bp. The composite structure of the longer alleles closely resembles that of the 12 human D12S67 alleles (229-273 bp). The enormous species variation in the fragment size range, with the smallest allele found in Macaca mulatta (108 bp) and the largest (364 bp) in Gorilla gorilla gorilla strongly indicates that D12S67 has been subjected to recurrent mutations over the course of primate evolution including a large deletion and/ or insertion event.
