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.
