elegans have been produced, and it was found that when they have a balanced sex and autosome ratio (4X:4A), they are still hermaphrodites, and as with diploids, a low percentage of those still produce approximately 1% male progeny (Nigon 1949a, 1949b, 1951a, 1951b, cited by Madl & Herman 1979).
13) (2015) reported a balanced sex autosome translocation t(X;1)(q21;p32) in a female patient who presented with primary amenorrhea without dysmorphic features or developmental delay.
Putative paralog motifs were filtered for this application such that 1 target paralog is mapped to a chromosome of interest (chromosomes 18 or 21) and a paired paralog sequence is mapped to an alternative autosome.
A possible reason for this variation can be amplification of a short arm in an originally large subtelocentric autosome.
1993; Norn, 1997; Deeb and Kohl, 2003), whereas the blue pigment gene is located on an autosome, chromosome 7 at 7q32 (Nathans et al.
The large Y chromosome in both species likely represents centric fusion between an autosome and a morphologically cryptic Y chromosome, giving rise to a situation of multiple sex chromosomes: [X.
X; autosome translocations are uncommon and are associated with a variable phenotype with an incidence of approximately 1:30,000 live births.
Second, since Chromosome 12 is an autosome, everyone has two copies and thus we need to describe both individual loci; thus the "G:G" or similar shorthand notation.
Such comparisons can be carried out on mitochondrial DNA (female parent's line), the Y chromosome (male parent's line), and the autosome chromosomes (both parents' lines).
The two karyotyped specimen of Oligoryzomys nigripes presented 2n = 62; NA = 82, due the variation in autosome fundamental number due to pericentric inversions (Yonenaga et al.
Interestingly, in contrast to hemophilia a and b, which are associated with mutations on the X chromosome, factor xi deficiency is linked to gene mutations on chromosome 4, an autosome.
In a few cases SRY gene is translocated to autosome, father is unaffected and may carry translocation and XX siblings have a 50% chance of being affected, XY siblings are unaffected.
