Gene conversion A non-reciprocal transfer of an allelic difference from one chromosome to its homologue. Crossover A precisely reciprocal breakage of two DNA molecules followed by rejoining with exchanged partners. Loss of heterozygosity Loss of an allelic difference between two chromosomes in a diploi...
We conclude that a gene's position in the chromosome, rather than its sequence, determines the time of replication. We suggest that the differences in association with gene rearrangement result from changes in the proximity of the affected gene to sites that control the temporal order of ...

Here we investigated the involvement of gonadotropins in sex change by determining the changes in gonadotropin receptor (GtHR) gene expression during the onset of sex change from female to male and male to female. The expression of the GtHR was found to be confined to the active gonad of the...
during sex change in clownfish, with the aromatase gene playing a central role, both in the brain and the gonad. This work constitutes the first genome-wide study in a social sex-changing species and provides insights into the genetic mechanism governing social sex change and gonadal restructuring...
How different is the evolution of sex-biased gene expression between plants and animals? A commentary on: 'Sexual dimorphism and rapid turnover in gene expression in pre-reproductive seedlings of a dioecious herb' This article comments on: Guillaume G. Cossard, Melissa A. Toups and John R....
After these gene duplications, a substantial number of old duplicate genes have also been lost in each lineage. Because many old duplicate genes were lost, it is likely that lost genes had already been differentiated from other groups of genes at the time of gene loss. We conclude that both...
A single nucleotide polymorphism (SNP) in the c gene, which encodes a trihelix transcription factor, causes nonshattering in O. sativa. However, the genetic mechanism of nonshattering in O. glaberrima is poorly understood. We conducted an association analysis for the coding sequences of SH3/...
for the change of a gene within the genome by homologous recombination of intact mammalian cells leads to a dna sequence which homolog to changing gene is, however, in at least one nucleotide mutation, deletion or insertion of the sequence differs by mikroinjektion in corresponding cells and wins...
The genetic size was assessed by using measures based on the probability of identity-by-descend of genes (coancestry,f, and effective population size,Ne), as well as measures based on probability of gene origin (effective number of founders,fe, effective number of founder genomes,fg, and ...
