They comprise a sister lineage of birds and have no sex chromosome.
2
To address the possibility of sex chromosome involvement, reciprocal F1 hybrids were produced.
3
Sometimes the abnormality involves a missing or an extra sex chromosome.
4
That makes KS the most common of the sex chromosome abnormalities.
5
However, we find no evidence for large amplicons identified in other sex chromosome systems.
6
In addition, monotremes feature an extraordinary multiple sex chromosome system.
7
All the eggs contain what is known as the "X" type of sex chromosome.
8
Men and women are identical apart from the sex chromosome which distinguishes you as male or female.
9
We tested this model by asking how newly evolving sex chromosome arms in Drosophila miranda acquired dosage compensation.
10
They have elongated sperm like chicken and a complex sex chromosome system with homology to chicken sex chromosomes.
11
Two of four patients in this group showed trisomy 22; the remaining two showed a loss of a sex chromosome.
12
Although the PAR fulfills key meiotic functions in most mammals, several exceptional species lack PAR-mediated sex chromosome associations at meiosis.
13
The results reported by the participants were highly concordant for the determination of modal chromosome count and sex chromosome designation.
14
Hormonal and sex chromosome mechanisms interact in the sex-specific control of certain diseases, sometimes by opposing the action of the other.
15
RNA has been classically known to play central roles in biology, including maintaining telomeres, protein synthesis, and in sex chromosome compensation.
16
In order to delineate the point of origin of sex chromosome specific silencing in mammals we investigated whether MSCI exists in platypus.
