Chromosomal mosaicism and maternal cell contamination in chorionic villi cultures
Abstract:
In a series of 110 chromosome analyses, after chorionic villus sampling, mosaics were found in 3 out of 106 long term cultures. In all 3 cases, subsequent amniotic fluid cell cultures showed normal karyotypes. Maternal cell contamination was encountered in one long term culture derived from carefully dissected chorionic villi.

Crossing Over
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process called synapsis.

Meiosis vs. Mitosis
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
