Me me hade da melanin da launin ido?

Melanin, wani nau'in launi ne wanda ke ba da gudummawa ga gashinku da launin fatarku, shima yana taka rawa cikin launin iris.

Yayinda wasu idanun jariri shuɗi ne ko launin toka lokacin haihuwa, kamar yadda binciken da aka ambata a sama, da yawa suna da launin ruwan kasa daga farawa.

Kamar yadda melanocytes a cikin iris ke amsawa ga haske da kuma ɓoye melanin, Cibiyar Kwararrun Ilimin Yara ta Amurka (AAP) ta ce launin irises na jariri zai fara canzawa.
