Abstract

A monogenetic factor determining basic pigmentation in Biomphalaria straminea follows simple. Mendelian inheritance and has at least three alleles, as in B. glabrata. Wild type pigmentation with black body, mantle collar and eyes is dominant; albino with no black pigment is recessive; and "blackeye" pigmentation, deficient in black pigment in body and mantle collar, is recessive to wild type but dominant over albino.

摘要

决定淡黄双脐螺基本色素沉着的单基因因子遵循简单的孟德尔遗传，并且如同光滑双脐螺一样至少有三个等位基因。具有黑色身体、外套膜领和眼睛的野生型色素沉着是显性的；没有黑色色素的白化型是隐性的；而“黑眼”色素沉着，身体和外套膜领缺乏黑色色素，相对于野生型是隐性的，但相对于白化型是显性的。
