Patterns and Mechanisms of Sex Ratio Distortion in the Collaborative Cross Mouse Mapping Population

Tags: , ,
B. A. Haines, F. Barradale and B. L. Dumont,  bioRxiv,  2021.
In species with single-locus chromosome-based mechanisms of sex determination, the laws of segregation predict an equal ratio of females to males at birth. Here, we show that departures from this Mendelian expectation are commonplace in the 8-way recombinant inbred Collaborative ...

Tags: , ,
T. Zhang, M. Mudgett, R. Rambabu, B. Abramson, X. Dai, T. P. Michael and Y. Zhao,  Nature Communications,  12:3854. 2021.
Sexual reproduction constrains progeny to inherit allelic genes from both parents. Selective acquisition of target genes from only one parent in the F1 generation of plants has many potential applications including the elimination of undesired alleles and acceleration of trait ...

Haldane’s duel: intragenomic conflict, selfish Y chromosomes and speciation

Tags: , ,
S. W. Roy,  Trends in Genetics,  2021.
Haldane?s rule, which states that the heterogametic sex (XY or ZW females) fares more poorly in interspecific hybrids, is generally attributed to absence of one of the two species' X/Z chromosomes. However, Haldane?s rule is also observed in mouse placentas despite paternal X ...
