Chromosome band numbering
WebDec 2, 2016 · A resolution of 350–500 bands corresponds to chromosomes in the late metaphase and high resolution (about 850 bands) corresponds to chromosomes in the mid-prophase. A 2000-band resolution chromosome band may contain approximately 1.5 Mb of DNA, whereas a 350-band resolution chromosome may contain 7–10 Mb of DNA [ 12 ]. WebWe present cases of Y-linked male infertility in terms of (i) anomalies of the Y chromosome structure/number; (ii) Y chromosome misbehavior in a normal genetic background; (iii) Y chromosome copy number variations (CNVs). We discuss possible explanations of male infertility caused by mutations, lower or higher number of copies of otherwise wild ...
