DNA extraction and yield determination
Male brood pouches were dissected and embryos were
individually preserved in 96-well plates. Embryos were
randomly chosen for DNA extraction. Genomic DNA was
extracted from adult fin clips and whole embryos with
DNeasy 96 Tissue Kits on a BioRobot 8000 (QIAGEN)
following the manufacturer’s recommendations. DNA
samples were diluted to a common concentration of
2 ng/
μ
L prior to performing microsatellite analyses.
