СРОЧНО!!! ДАЮ МАКС БАЛЛЫ!!!
Среди дрозофил никогда не наблюдалось мух с синими или или зелеными глазами.
Какова вероятность обнаружения указанных мутаций в будущем?

Автор ответа: ulashmi

В геноме дрозофил нет каких-то предпосылок, которые нужны для появления мутаций в виде синих или зеленых глаз, хотя подобные окраски глаз нередко наблюдаются у других видов насекомых. Для дрозофил эти мутации являются по каким-то причинам "невозможными", так что вероятность обнаружения практически нулевая.
