To evaluate whether XX vs. XY sex chromosome complements differentially regulate sexually dimorphic humoral immune responses to HKSP immunization, the FCG mouse model was utilized (Additional file1: Fig. S1; [35,36,63]). Ovary-bearing females with XX (XXF) or XY (XYF) sex chromosomes and tes...
It was noted only recently that the mammalian X/Y sex chromosome system originated late in our therian ancestors. The question is, what makes the X/Y sex chromosome system so special that it has replaced the original Z/W sex chromosome system? Two classes of genes are overrepresented on the...
We fed male and female XX and XYLdlr−/−mice a Western diet for 4 months to examine effects of sex chromosome genotype on serum lipids and atherosclerosis. To separate the contribution of sex chromosomes and sex hormones, male and female mice of each sex chromosome genotype were either go...
The Accumulation of Sexually Antagonistic Genes as a Selective Agent Promoting the Evolution of Reduced Recombination between Primitive Sex Chromosomes William R.

Well, here’s the twist. Unlike these systems, which receive autosomes from both parents, male honey bees andantsreceive chromosomes only from the female parent (the Queen). This means that they develop from unfertilized (haploid) eggs and don’t have a father, whereas fertilized (diploid)...
Turtles demonstrate variability in sex determination and, hence, constitute an excellent model for the evolution of sex chromosomes. Notably, the sex determination of the freshwater turtles from the family Chelidae, a species-rich group with wide geograp

XY sex chromosome complement, compared with XX, in the CNS confers greater neurodegeneration during experimental autoimmune encephalo- myelitis. Proc ......
Replication banding patterns were induced in the chromosomes of Gastrotheca riobambae by treating cell cultures with 5-bromodeoxyuridine (BrdU) and deoxythymidine (dT). In particular, the time sequence of replication of the highly differentiated XY/XX sex chromosomes was meticulously analyzed throughout...

Answer to: Explain why people with XY-chromosomes are more likely than XX-individuals to have the recessive x-linked single-gene disorders,...
