... publications to understand how the sex chromosome complement affects the fertility of XY oocytes by comparing with XX and monosomy X (XO) oocytes. Summary: The results highlight 2 folds disadvantage of XY oocytes over XX oocytes: (1) the X and Y chromosomes fail to pair during the meiotic prophase I, resulting...

...Michelle C. Maier; Molly-Rose A. McInerney; Jennifer A. Marshall Graves; Fadi J. Charchar The mammalian Y chromosome has evolved in many species into a specialized chromosome that contributes to sex development among other male phenotypes. This function is well studied in terms of protein-coding...

In this paper, we describe a 47,XXY female who was pregnant with a fetus of the same...

We analyzed the copy...

... multiplexing of 2 primer pairs. We have developed a novel sexing PCR using a single primer pair that amplifies fragments from the X and the Y chromosome with a clear size difference between the respective amplicons. This assay provides a rapid and reliable method to identify the genetic sex of mice across...

King Multi-copied gene families are prevalent in mammalian genomes, especially within the Y chromosome. Testis specific protein Y-encoded (TSPY) is present in variable copy number...

... and Y chromosomes and the difficulty in identifying Y-specific markers indicate that X and Y chromosomes in salmonids have a large pseudoautosomal region and a small sex determining region. Linkage analyses suggest that either SEX differs in different lineages or else has remained the same and moved...

... duplication of the autosomal gene dmrt1 onto another autosome, thus generating a new Y chromosome. Dmrt1bY emerged about 10 million years ago and is restricted to several Oryzias species, indicating that the Y chromosome of the medaka is evolutionarily much younger than mammalian and bird sex chromosomes...
