The Eutherian Pseudoautosomal Region.
The pseudoautosomal region (PAR) is a unique segment of sequence homology between differentiated sex chromosomes where recombination occurs during meiosis. Molecular and functional properties of the PAR are distinctive from the autosomes and the remaining regions of the sex chromosomes. These include a higher rate of recombination than genome average, bias towards GC-substitutions and increased...
متن کاملA Review of Mycoplasma in Laboratory Mice
Mycoplasma are small, cell-free bacteria enclosed by a membrane. These bacteria belong to the class of Mollicutes, the order of Mycoplasma tales, and the genus of Mycoplasma. There are more than 100 identified species of mycoplasma. The ratio of cytosine to guanine in its DNA is 23–40% and its genome size is 1350–600 kb. Mycoplasma require cholesterol to grow, and the temperature su...
متن کاملRecombination in the Human Pseudoautosomal Region PAR1
The pseudoautosomal region (PAR) is a short region of homology between the mammalian X and Y chromosomes, which has undergone rapid evolution. A crossover in the PAR is essential for the proper disjunction of X and Y chromosomes in male meiosis, and PAR deletion results in male sterility. This leads the human PAR with the obligatory crossover, PAR1, to having an exceptionally high male crossove...
متن کاملCo-segregation of intermale aggression with the pseudoautosomal region of the Y chromosome in mice.
The sexual dimorphism of aggression has led to a search for its Y chromosomal correlates. We have previously confirmed that initiation of attack behavior against a conspecific male is Y-dependent in two strains of laboratory mice (NZB and CBA/H). We provide evidence that the non-pseudoautosomal region of the Y is not involved and that only the pseudoautosomal region of the Y is correlated with ...
متن کاملA gene spans the pseudoautosomal boundary in mice.
The X and Y chromosomes of the mouse, like those of other mammals, are heteromorphic over most of their length, but at the distal ends of the chromosomes is a region of sequence identity, the pseudoautosomal region (PAR), where the chromosomes pair and recombine during male meiosis. The point at which the PAR diverges into X- and Y-specific sequences is called the pseudoautosomal boundary. We h...
