Zebrafish Synteny
Go to www.ensembl.org Find the Rhodopsin (rho) gene for zebrafish. Go to the Location tab.
(a) Click Synteny at the left. Are there any syntenic regions in Japanese medaka HdrR If so, which chromosomes are shown in this view?
(b) Stay in the Synteny view. Is there a homologue in Japanese medaka HdrR for zebrafish rho? Are there more genes in this syntenic block with homologues?
(a) Change the species to Japanese medaka HdrR next to the image. Yes, there are multiple syntenic regions in Japanese Medaka to zebrafish chromosome 8, which is in the centre of this view. Japanese medaka HdrR chromosomes 4, 7, 9, and 12 have syntenic regions to zebrafish chromosome 8.
(b) Scroll down to the bottom of the page. There is a homologue in Japanese medaka HdrR of zebrafish rho. Click 15 upstream genes or 9 downstream genes to compare the genes between zebrafish and Japanese medaka HdrR in this syntenic block.
