2014年11月6日 · It is located between 3.5 Mb of short-arm and 86.0 Mb of long-arm sequence, confirming that the mouse Y is the only acrocentric chromosome among all the other telocentric mouse chromosomes (Ford, 1966, McLaren et al., 1988, Roberts et al., 1988).

The short arm of the Y chromosome (Yq) consists primarily of genes shared with the X chromosome and retained since the sex chromosomes diverged from the ancestral autosome pair. These genes are interspersed with blocks of segmental duplications (light grey).

Marker evidence for DSBs occurring in the non-PAR region of the Y chromosome is limited. Nevertheless, historically it has been documented that recombination can occur within the mouse Y short arm (Yp) when an additional Yp segment is attached distal to the X and/or the Y pseudoautosomal region (PAR).

We sequenced the MSY (Male-Specific region of the Y chromosome) of the C57BL/6J strain of the laboratory mouse Mus musculus. In contrast to theories that Y chromosomes are heterochromatic and gene poor, the mouse MSY is 99.9% euchromatic and ...

We demonstrate that the H-Y- variant of Sxr (Sxr') arose by a partial deletion within the Sxr region. Also, we show that intrachromosomal recombination between the Y short arm and Sxr' can sometimes occur during male meiosis, restoring the deleted DNA sequences and resulting in an H-Y+ mouse (male 719 in this paper).

Cytological analysis of the mouse Y* chromosome revealed a complex rearrangement involving acquisition of a functional centromere and centromeric heterochromatin and attachment of this chromosomal segment to the distal end of a normal Y* chromosome. This rearrangement positioned the Y* short-arm reg …

1994年1月1日 · The small mouse Y chromosome is composed of a minute short arm (Yp) and a long arm (Yq). The telomeric end of Yq is known as the “pseudoautosomal region” and shares homology with a region of the X chromosome. This region is responsible for the obligatory pairing and exchange of the X and Y chromosomes during male meiosis.

2021年9月9日 · Several lines of evidence indicate that the male-specific region on long arm of the Y chromosome (MSYq) in mouse is replete with highly repetitive mouse-specific sequences that are expressed in spermatids [9,10,11,12].
