A family consisting of a mother (M), father (F) and their
four children (C1-C4) were all genotyped at a simple
sequence repeat (SSR) molecular marker IMS19.
Human populations have four known alleles at IMS19,
consisting of 8 to 11 repeats of the sequence CAG
(alleles r8, r9, r10, and r11). The PCR products were run
on a gel, as shown below.
Which child(ren), if any, could not be the biological
child of the two parents?
