Müllerian Mimicry
Müllerian mimicry is a natural phenomenon in which two or more well-defended species, often foul-tasting and sharing common predators, have come to mimicry, mimic each other's honest signal, honest aposematism, warning signals, to their mutualism (biology), mutual benefit. The benefit to Müllerian mimics is that predators only need one unpleasant encounter with one member of a set of Müllerian mimics, and thereafter avoid all similar coloration, whether or not it belongs to the same species as the initial encounter. It is named after the German Brazilian, German Brazilian naturalist Fritz Müller, who first proposed the concept in 1878, supporting his theory with the first mathematical model of frequency-dependent selection, one of the first such models anywhere in biology. Müllerian mimicry was first identified in tropical butterfly, butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals such as Poiso ...

Müllerian Duct
The paramesonephric ducts (or Müllerian ducts) are paired ducts of the embryo in the reproductive system of humans and other mammals that run down the lateral sides of the genital ridge and terminate at the sinus tubercle in the primitive urogenital sinus. They form in both sexes during 6th week of fetal development. In the female, go on to form the fallopian tubes/ oviducts, uterus, cervix, and the upper one-third of the vagina. In males fetuses, they are normally made to regress by anti-Müllerian hormone which begins to be secreted by the testes during 8th week of fetal development. Each maramesonephric duct is situated just lateral to the mesonephric ducts (Wolffian duct) of the same side. Development The female reproductive system is composed of two embryological segments: the urogenital sinus and the paramesonephric ducts. The two are conjoined at the sinus tubercle. Paramesonephric ducts are present on the embryo of both sexes. Only in females do they develop into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
