Figure 5. Semi-RT-PCR measurement of Tyrp2 gene expression in retinas and feather bulbs from ducks with different plumage types.

Lanes 1–6: cDNA from 2 replicates of white, white-black and black plumage duck eyes; lanes 7–14: cDNA from 2 replicates of W-W, B-WB, W-WB and B-B feather bulbs; lanes 15–22: β-actin, samples are the same as lane 7–14, respectively. M: Marker I, six bands at 600, 500, 400, 300, 200, and 100 bp.
