GeneScan results for locus CJ1 for one individual. Allele size is reported as the number of base pairs (red peaks are size standard, blue shaded peaks are alleles).
Liver and spleen tissues for this individual appear to be chimeric, exhibiting three peaks for one locus; while lung, muscle, and gonad tissue only have two peaks.
Fraternal twins may be fertilized by sperm from two males. Therefore, chimerism may allow an individual to express genes from TWO fathers.
Genotypes of an individual differ across tissues.
However, chimerism is NOT limited to bone marrow tissues.
We would like to thank the National Science Foundation, UNL Special Funds, UNL Layman's Grant, UNL Initiative for Ecological and Evolutionary Analysis, Sigma Xi and American Society of Primatologists for grants supporting this research. We would also like to thank Justin Meeker, Alicia Startzer, Sara Brant, Jeffrey Fite, Erin Kinnally, Mike Bessert and Annie Paradis for help in sample collection and analysis.
Genescan results for additional microsatellite loci (CJ13, CJ14) reveal that three alleles may be found in a multitude of tissues including gonad and heart tissue.
