Can the classical euchromatic
variants of 9q12/qh+ cause recurrent abortions?
3A) an euchromatic
nucleus and a cytoplasm containing rough endoplasmic reticulum, Golgi bodies, and mitochondria.
Both types of Bs seemed to be nonhomologous, the acrocentric type always forming, when in double dose, a chiasmate bivalent that co-oriented along with the autosomes in metaphase I, while both arms of the metacentric B paired and formed a chiasma between their euchromatic
ends (White 1951b).
Each germ cell (~20 [micro]m) has an eosinophilic cytoplasm and a big euchromatic
nucleus with an evident nucleolus.

A peer review assessment of the research has already confirmed that the finished sequence now covers more than 99% of the euchromatic
(or gene-containing) portion of the human genome and was sequenced to an accuracy of 99.
To describe the different C-banding patterns, three autosomal morphs, denoted A, B, and C, were recognized on the basis of previous reports (10,12) (Figure 2): A morph (a subterminal C-heterochromatic block is present at one chromosomal end; the other end is euchromatic
or has a very small C-band); B morph (C-heterochromatic blocks are clearly present at both chromosomal ends); and C morph (the chromosome is totally euchromatic
or has a very small C-band).
All of the chromosomes in the Arrhenatherum accessions examined were generally euchromatic
, with most telomeres and secondary constrictions having C-bands.
For example, one of the seminal discoveries in molecular population genetics is that the level of nucleotide polymorphism across the euchromatic
genome is correlated with recombination rate.
