Genotypes suppressing meiotic drive of a B-chromosome in the mealybug, Pseudococcus obscurus

Tags: , ,
Nur, UB, B. L. H.,  Genetics,  110:73-92. 1985.
The rate of transmission (k) of a supernumerary B chromosome in male mealybugs is shown tq depend strongly on the chromosome set of materpal origin. When both parents came from an isofemale line in which the frequency of the B chromosome increased rapidly and stabilized at a mean ...

Sex-chromosome meiotic drive in Drosophila melanogaster males

Tags: , ,
McKee, B,  Genetics,  106:403-422. 1984.
In Drosophila melanogaster males, deficiency for X heterochromatin causes high X-Y nondisjunction and skewed sex chromosome segregation ratios (meiotic drive). Y and XY classes are recovered poorly because of sperm dysfunction. In this study it was found that X heterochromatic ...

Wu, CI,  Theoretical Population Biology,  24:107-120. 1983.
A model is proposed to analyze the behavior of autosomal suppressor modifiers of "Sex-Ratio" meiotic drive in drosophila. These modifiers, if neutral in fitness, are expected to increase because they tend to be associated with the rare sex (males). However, selection operating on ...

A theoretical-analysis of the effects of sex-chromosome aneuploidy on X-chromosome and Y-chromosome meiotic drive

Tags: ,
Lyttle, TW,  Evolution,  36:822-831. 1982.
Extra sex chromosomes are normally detrimental to the individual carrying them. In XY (or WZ) sex determining systems, an extra X chromosome in the homogametic sex generates enough X-autosome imbalance to usually cause inviability, or at least sterility. On the oth- er hand, ...

Tags: , ,
Youngson, JW, H. M.; Wood, R. J.,  Genetica,  54:335-340. 1981.
The Distorter gene D in Aedes aegypti shows meiotic drive when associated with the male determining M gene, causing sex ratio distortion in favour of males. The fertility of Distorter (MD /ms) and normal (M/m-) males has been compared after mating them to a series of 20 females ...

A 2-locus model for polymorphism for sex-linked meiotic drive modifiers with possible applications to Aedes aegypti

Tags: , ,
Maffi, GJ, S. D.,  Theoretical Population Biology,  19:19-36. 1981.
A two-locus model is presented which shows the possibility of maintaining a polymorphism for modifiers of sex-linked meiotic drive in the absence of fitness differences. The model is very similar to the situation actually found in some laboratory strains of the mosquito Aedes ...

Experimental population-genetics of meiotic drive systems .3: Neutralization of sex-ratio distortion in Drosophila through sex-chromosome aneuploidy

Tags: , , , ,
Lyttle, TW,  Genetics,  98:317-334. 1981.
Laboratory populations of Drosophila melanogaster were challenged by; pseudo-Y drive, which mimics true Y-chromosome meiotic drive through the; incorporation of Segregation Distorter (SD) in a T(Y;2) complex. This causes; extreme sex-ratio distrotion and can ultimately lead to ...
