| The prevalence of sex chromosome abnormalities in the mare has been reported to be less than 3%. |
|
| The main sex chromosome systems characterizing sex determination in animals are represented in plants. |
|
| The degeneration cycle may be reset by formation of neo sex chromosomes by fusion between a sex chromosome and an autosome. |
|
| In embryos with abnormal sex chromosome complexes, the number of X chromosomes is apparently of little significance. |
|
| Males and females have different sex chromosome constitutions, thus, the mechanism of sex determination is genetically mediated and demonstrates a paternal origin effect. |
|
| Sex chromosome abnormalities sometimes cause the failure of reproductive organs to function normally, or they can result in unviable gametes lacking a normal sex chromosome complement. |
|
| Another variation of numerical sex chromosome abnormalities is X chromosome mosaicism, which may be the third most common sex chromosome abnormality described in the horse. |
|
| This change in viewpoint rationalizes a change in experimental strategies for dissecting sex chromosome effects. |
|
| To define the prevalence of low-level sex chromosome mosaicism in a cohort of infertile men. |
|
| One pair is the sex chromosome which among other things determines gender. |
|
| Reports of the coming death of the male sex chromosome are greatly exaggerated, say scientists, whose work will raise a collective cheer from at least half the population. |
|
| These technologies would not be permitted except for health purposes, for example, to screen for serious medical conditions that are carried on a sex chromosome and are more likely to occur in one gender than the other. |
|
| Sex chromosome abnormalities are more common and tend to have less-drastic effects than autosomal abnormalities. |
