Figure 3. The confocal representation of the positioning of sSMC and chromosome 15 centromeres demonstrated in two geometrical perspectives obtained by confocal microscopy.
Red: centromere-specific probe for chromosome 15; green: SMAD6 gene locus (15q22.31). Scale bar: 3.0 μm. (a) Spermatozoa bearing sSMC (sSMC+) with two red and one green FISH signals. (b) Spermatozoa without sSMC (sSMC−) with one red and one green FISH signals.
