Fig. 1. Di-nucleotide microsatellite genotypes of a female blue shark with 16 embryos. Lanes 1-16 show embryo genotypes. P1-P4 are paternal alleles, showing multiple paternity. Pg -13 is the locus designation. Lane M is a molecular size marker. (From: P. Prodohl, D. Chapman and M. Shivji, unpublished data).

Fig. 2. Tri-nucleotide microsatellite genotypes of 2 bonnethead litters.
A. Mother and 8 embryos genotyped with microsatellite locus St-4.1.
B. Mother and 13 embryos genotyped with microsatellite locus St-1.
P1-P2 are paternal alleles. For both litters, these and additional genotyping data from six loci indicate single paternity (From: D. Chapman, P. Prodohl, J. Gelsleichter, C. Manire and M. Shivji, unpublished data).
