Results of the microsatellite analysis on chromosome 11. MSA results for the 11 investigated markers spread along chromosome 11. Parental origin is indicated by colours. For III-5 and III-6 paternal contribution could only be detected for one marker (D11S1984, 11p15.5). For the short arm of chromosome 11, the twins have inherited different paternal but the same maternal allele. For individual III-6 two crossing over events, one on the paternal and one on the maternal allele, were observed. The breakpoints on the paternal allele cannot be clearly denoted as the results for two markers (D11S1392 and D11S2000) can be assigned to both alleles. This is indicated by a two colour scheme. For the maternal allele, the event took place between the last marker for the short and the first marker for the long arm of the chromosome. Asterisk indicates a hemi- or homozygous state, which is not distinguishable by this method.
