COLOUR INHERITANCE IN ICELANDIC SHEEP 125 í naggrísum finnast þannig dreifðar litamóðurfrunrur í skinninu í hvítu blett- unum, og í dropóttu sauðfé tefjast þessar frumur ekki meira en það á ferð sinni, að þær eru komnar í hvítu blettina í skinninu, áður en síðustu þelhára- sekkirnir myndast, þannig að dökkir blettir koma fram í þelinu á hvítu svæð- unurn á dropóttu fé, en toghárin á þessum blettum eru öll hvít.
