Figure 3: Principal component analysis of miRNAs from zebrafish gonads and gametes.
From: Dynamics of miRNA transcriptome during gonadal development of zebrafish

(a) Clustering of miRNAs according to gonadal sex and developmental advancement. (b) Clustering of miRNAs in gametes versus respective gonad samples derived from sexually mature 24-week-old zebrafish. Blue and red colors denote male and female sex samples, respectively, while green color marks sexually undifferentiated 3-week-old juvenile gonad.
