Horsfield's fruit bat Horsfield's fruit bat Horsfield's fruit bat ("Cynopterus horsfieldii") is a species of megabat native to South East Asia. It is named for Thomas Horsfield, an American naturalist who presented the type specimen to the British Museum. Horsfield's fruit bat is a medium-sized megabat, intermediate in size between flying foxes and pygmy fruit bats. Adults weigh around , and have light-grey to brown fur, with a reddish-brown or orange mantle around the shoulders. In some males, the mantle extends across the chest, and the fur is often brighter in colour than in females. The rim of the ears and the skin
Wild type all gene loci exist in a variety of allelic forms, which vary in frequency throughout the geographic range of a species, and that a uniform wild type does not exist. In general, however, the most prevalent allele – i.e., the one with the highest gene frequency – is the one deemed as wild type. The concept of wild type is useful in some experimental organisms such as fruit flies "Drosophila melanogaster", in which the standard phenotypes for features such as eye color or wing shape are known to be altered by particular mutations that produce distinctive phenotypes, such as "white
