Evolution by gene duplication: an update

TL;DR: Detailed molecular characterization of individual gene families, computational analysis of genomic sequences and population genetic modeling can all be used to help uncover the mechanisms behind the evolution by gene duplication.
Journal ArticleDOI

X-inactivation profile reveals extensive variability in X-linked gene expression in females

TL;DR: A comprehensive X-inactivation profile of the human X chromosome is presented, representing an estimated 95% of assayable genes in fibroblast-based test systems, and suggests a remarkable and previously unsuspected degree of expression heterogeneity among females.
Journal ArticleDOI

Altruism and Related Phenomena, Mainly in Social Insects

TL;DR: With better knowledge of heredity and with more facts regarding the social insects to draw upon, Weismann recognized the possible conflict between intergroup and intragroup selection in the evolution of worker attributes.
Journal ArticleDOI

The DNA sequence of the human X chromosome

Mark T. Ross, +282 more
- 17 Mar 2005 - 
TL;DR: This analysis illustrates the autosomal origin of the mammalian sex chromosomes, the stepwise process that led to the progressive loss of recombination between X and Y, and the extent of subsequent degradation of the Y chromosome.

Gene Action in the X -chromosome of the Mouse ( Mus musculus L.)

TL;DR: Ohno and Hauschka1 showed that in female mice one chromosome of mammary carcinoma cells and of normal diploid cells of the ovary, mammary gland and liver was heteropyKnotic and suggested that the so-called sex chromatin was composed of one heteropyknotic X-chromosome.
Journal ArticleDOI

A morphological distinction between neurones of the male and female, and the behaviour of the nucleolar satellite during accelerated nucleoprotein synthesis.

TL;DR: It appears not to be generally known that the sex of a somatic cell as highly differentiated as a neurone may be detected with no more elaborate equipment than a compound microscope following staining of the tissue by the routine Nissl method.
Journal ArticleDOI

The normal human female as a mosaic of x-chromosome activity: studies using the gene for g-6-pd-deficiency as a marker

TL;DR: It seems necessary to assume that there is, at least for some period of time during development, randomization of the active and inactive chromosome among the dividing cells of the body.
Journal ArticleDOI

Cellular localization of immunoglobulins with different allotypic specificities in rabbit lymphoid tissues

TL;DR: The cellular localization of allotypes in rabbit lymphoid tissues has been studied by immunofluorescence and double staining for two allotypes controlled by genes at different loci has shown the presence of cells containing immunoglobulins that lack one allotype.
Book ChapterDOI

The phenomenon of position effect.

TL;DR: This chapter highlights the major developments in the field of position effect taking Drosophila as an example, together with a discussion of the properties and possible mechanisms.
