Figures 3-10 from: Brito P, Targueta C, Arruda W, Santos F, Bastos R (2019) The sexual dimorphic inguinal glands of the frog species Ololygon centralis (Anura: Hylidae) at light and transmission electron microscopy. Zoologia 36: 1-9. https://doi.org/10.3897/zoologia.36.e29356
Figures 3-10 Photomicrographs of histological sections of the male inguinal gland region of O.centralis. (3–6, 8) Histological sections stained with HE. 3) Section of skin from the peripherical region of the inguinal gland. Notice that only mucous glands are present. 4) Low magnification micrograph showing the presence of many syncytial glands (g), with arrows indicating the lateral limits of the inguinal gland. (4–6) Major magnifications of the glandular apical portion, with many melanocytes (m), mucous glands (mc) and myoepithelial cells (open arrows). Note the glandular ducts (dc). 7) Histological section submitted to PAS reaction. Notice that only some cells of the mucous glands (mc) exhibit a positive reaction (arrowheads). (8) Major magnification of the lateral base portion of the syncytium, with colloidal secretion (s) in syncytium cytoplasm. Note also a blood vessel in the connective tissue. (9) Methacrylate section treated with potassium permanganate and oxalic acid and stained with Nile blue. Notice the bleached melanocytes (m) and some syncytial cytoplasmic projections (*) through the glandular secretion (s). (10) Methacrylate section stained with toluidine blue. Notice the pale blue color of the secretion suggesting it is alkaline, contrasting with the dark blue color of the glandular syncytium (gs). (e) epidermis; (d) dermis; (black open arrow) myoepithelial cells; (c) blood cells. Scale bars: 5, 6, 8 = 10 μm, 3, 7, 9, 10 = 20 μm; 4 = 200 μm.

Figures 16-18 (16) The basal portion of the syncytium with digitiform projections (p) and the clear space (*) between them and the myoepithelial cells. Notice the myoepithelial cells nuclei (n) and the collagen fibrils. (17) Detail of the connective tissue between two neighbor alveoli, with myoepithelial cells (m) and collagen fibrils (c). (18) The basal portion of a syncytium with intricate projection labyrinth. Notice the syncytium nucleus with irregular outline (n). Scale bars: 18 = 1 μm, 16, 17 = 3 μm.

Rapid evolution of sexual size dimorphism facilitated by Y-linked genetic variance data set
<p>The three datasets were collected to study the genetic architecture of sexual size dimorphism in the seed beetle <i>Callosobruchus maculatus</i> (Quantitative_genetics_data_set), the response of sexual dimorphism to artificial selection (artificial_selection_data_set) and to isolate and quantify the effect of Y haplotypes on male body size (Y_introgression_data_set).</p> <p><u>Quantitative genetics:</u> A four generation breeding design with pedigree information for 8022 individuals and body size measurements for 7356 individuals. The breeding design and sample size of the study allows to partition genetic variances into additive autosomal, additive sex-linked, autosomal dominance and X-linked dominance variance.</p> <p><u>Artificial selection:</u> Family level phenotypic data over 10 generations of artificial selection using direct progenitors of the quantitative genetics experiment in 5 different selection regimes (random selection [C], sexually antagonistic selection, for increased sexual dimorphism [SA], sex limited selection; for small males [SL1], for large females [SL2], for large males [SL3]), each selection regime was replicated by two replicate lines, resulting in 10 selection lines.</p> <p><u>Y introgression:</u> We followed the Y lineage (paternal founder line) from the quantitative genetics experiment over the course of the artificial selection, and after the selection we introgressed each remaining Y lineage into an isogenic background, by 13 generations of backcrossing of males with the isogenic females in order to isolate the Y-linked effect on male body size.</p>
