Meiotic drive in Lucilia cuprina and chromosomal evolution

Tags: ,
Foster, GGW, M. J.,  American Naturalist,  137:403-415. 1991.
In females heterozygous for pericentric inversions that alter the relative lengths of the long and short arms of a chromosome, crossing-over within the inversion can lead to unequal segregation at anaphase II, favoring the homologue with the more centrally located centromere. It ...

A comparative approach to the population genetics theory of segregation distortion

Tags: , , ,
Feldman, MWO, Sarah P.,  American Naturalist,  137:443-456. 1991.
Mathematical models of four well-known naturally occurring systems of segregation distortion are compared. These include the sex-ratio chromosome of Drosophila pseudoobscura, the Segregation Distorter (SD) complex of D. melanogaster, the t locus in Mus musculus, and the sex-ratio ...

X-chromosome segregation distortion in Drosophila

Tags: , , ,
Curtsinger, JW,  American Naturalist,  137:344-348. 1991.
The sex-ratio trait exhibits both discrete and continuous variation in Drosophila pseudoobscura. The discrete variation is caused by X-chromosome meiotic drive. The evolutionary forces maintaining the meiotic-drive polymorphism include strong viability selection against ...

Sex-ratio distortion caused by meiotic drive in mosquitos

Tags: , ,
Wood, RJN, M. E.,  American Naturalist,  137:379-391. 1991.
Meiotic-drive genes have been described in two species of mosquito, Aedes aegypti and Culex quinquefasciatus. In both species, a Y (M)-linked gene causes a change in sex ratio in favor of males. More is known about the Distorter gene (D) in A. aegypti, but the gene in C. ...

Why is Mendelian segregation so exact

Tags: , , ,
Crow, JF,  Bioessays,  13:305-312. 1991.
The precise 1:1 segregation of Mendelian heredity is ordinarily taken for granted, yet there are numerous examples of 'cheating' genes that perpetuate themselves in the population by biasing the Mendelian process in their favor. One example is the Segregation Distortion system of ...

Male sex-ratio trait in Drosophila pseudoobscura: Frequency of autosomal aneuploid sperm

Tags: , ,
Cobbs, GJ, L.; Gordon, L.,  Genetics,  127:381-390. 1991.
Males with the SR X chromosome show the "sex-ratio" (sr) phenotype in which they produce almost entirely daughters. The few sons (about 1%) are invariably sterile X/O males and result entirely from nullo-XY sperm. The "male-sex-ratio" (msr) phenotype is a modified form of sr in ...

The paternal-sex-ratio chromosome of Nasonia

Tags: , , ,
Werren, JH,  American Naturalist,  137:392-402. 1991.
Paternal sex ratio (PSR) is a supernumerary chromosome that is transmitted through sperm to fertilized eggs and then gains a transmission advantage by causing supercondensation of the paternal chromosomes (except itself). Because of haplodiploidy, this converts diploid females ...

Meiotic drive in Neurospora and other fungi

Turner, BCP, D. D.,  American Naturalist,  137:416-429. 1991.
When a gene complex called Spore killer is heterozygous, ascospores representing two of the four products of each meiosis are killed. Only those that receive the killer complex survive. This article reviews what is known of the mode of action of the Neurospora Spore killers, ...

Sex ratio polymorphism in Drosophila pseudoobscura

Tags: , , ,
Beckenbach, AT,  American Naturalist,  137:340-343. 1991.
I studied "sex-ratio" (SR) genotype frequencies in two populations of Drosophila pseudoobscura from southeastern Arizona: Bear Creek Canyon and Tucson. Wild-inseminated females were collected, their fecundities measured in the laboratory, and their SR genotypes inferred by ...

Meiotic drive of t-haplotypes – chromosome segregation in mice with tertiary trisomy

Tags: , ,
Agulnik, AIA, S. I.; Ruvinsky, A. O.,  Genetical Research,  57:51-54. 1991.
The properties of the t haplotypes, specific mutant states of the proximal region of chromosomes 17 in the house mouse, are of continuing interest. One such property is increased transmission of the t haplotype by heterozygous t/+ males to offspring. Using the reciprocal ...

Segregation distortion in Drosophila melanogaster: Genetic and molecular analysis

Tags: , ,
Temin, RGG, B.; Powers, P. A.; Lyttle, T. W.; Pimpinelli, S.; Dimitri, P.; Wu, C. I.; Hiraizumi, Y.,  American Naturalist,  137:287-331. 1991.
The Segregation Distorter (SD) complex in the centromeric region of chromosome 2 in Drosophila melanogaster is responsible for a naturally occurring and strong system of male meiotic drive. Earlier recombinational dissection and deletional analysis showed that the SD complex ...

Expression of meiotic drive elements Spore Killer-2 and Spore Killer-3 in asci of Neurospora tetrasperma

Tags: , , ,
Raju, NBP, D. D.,  Genetics,  129:25-37. 1991.
It was shown previously that when a chromosomal Spore killer factor is heterozygous in Neurospora species with eight-spored asci, the four sensitive ascospores in each ascus die and the four survivors are all killers. Sk-2K and Sk-3K are nonrecombining haplotypes that segregate ...

Meiotic drive of t haplotypes: chromosome segregation in mice with tertiary trisomy

Agulnik, AIA, Sergei I.; Ruvinsky, Anatoly O.,  Genetics Research,  57:51. 1991.
The properties of the / haplotypes, specific mutant states of the proximal region of chromosomes17 in the house mouse, are of continuing interest. One such property is increased transmission ofthe / haplotype by heterozygous // + males to offspring. Using ...

On the components of Segregation Distortion in Drosophila melanogaster 5: Molecular analysis of the SD locus

Tags: , ,
Powers, PAG, B.,  Genetics,  129:133-144. 1991.
Segregation Distorter (SD) is a naturally occurring meiotic drive system comprising at least three distinct loci: Sd, Rsp and E(SD). Heterozygous SD/SD+ males transmit the SD chromosome in vast excess over the normal homolog. The distorted transmission involves the induced ...

X-Y pairing, meiotic drive and ribosomal DNA in Drosophila melanogaster males

Tags: , ,
McKee, BD,  American Naturalist,  137:332-339. 1991.
One of the genotypic features responsible for sex-chromosome meiotic drive and sterility in Drosophila melanogaster males has now been defined clearly. Separation of a significant fraction of X euchromatin from the X pairing site causes either meiotic drive or sterility, ...

Segregation distorters

Tags: , , , , ,
Lyttle, TW,  Annual Review of Genetics,  25:511-557. 1991.
Segregation distorters are genetic elements that exhibit the phenomenon of meiotic drive; that is, the mechanics of the meiotic divisions cause one member of a pair of heterozygous alleles or heteromorphic chromosomes to be transmitted to progeny in excess of the expected ...

The genetics and evolutionary biology of meiotic drive: Preface

Lyttle, TW,  American Naturalist,  137:281-282. 1991.
More than 30 years have passed since the concept and the term meiotic drive were introduced by Sandler and Novitski. Many years have also passed since the preceding conference, which embraced both segregation distortion in Drosophial and transmission-distortion in the mouse, and ...

The Genetic Basis of Transmission-Ratio Distortion and Male Sterility Due to the t Complex

Tags: , ,
Lyon, MF,  American Naturalist,  137:349-358. 1991.
The abnormal transmission ratios observed in male mice heterozygous for a complete t haplotype have been shown by breeding studies to be due to three or more distorter genes acting on a responder gene. The action of the t form of the responder is relatively resistant to this ...

Meiotic drive against an autosomal supernumerary segment promoted by the presence of a B-chromosome in females of the grasshopper Eyprepocnemis plorans

Tags: ,
Lopezleon, MDC, J.; Camacho, J. P. M.,  Chromosoma,  100:282-287. 1991.
Twenty-seven out of 50 progeny analyses performed with specimens of the grasshopper Eyprepocnemis plorans were informative about the transmission of a supernumerary heterochromatic chromosome segment. The simultaneous presence of a B chromosome in some of the parents involved in ...

Sander,Larry – The father of meiotic drive

Tags: , ,
Lindsley, DL,  American Naturalist,  137:283-286. 1991.
The symposium at which the following papers were presented was deprived of what surely would have been a major intellectual contribution by the sudden death of its co-organizer, Larry Sandler, in February 1987. Larry was a leading contributor to the study of segregation ...
