1. of or relating to the Müllerian ducts, a pair of embryonic structures in vertebrates that develop into the female reproductive tract
Usage: anatomy; biology; medical
2. of or relating to Müllerian mimicry, a form of protective mimicry in which unpalatable species resemble each other
Usage: biology; ecology

Examples

• The Müllerian ducts are present in all mammalian embryos during early development.
• In females, the Müllerian ducts develop into the fallopian tubes, uterus, and upper vagina.
• Müllerian mimicry occurs when several toxic butterfly species evolve similar warning patterns.
• The absence of Müllerian ducts in males is due to anti-Müllerian hormone during fetal development.
• Scientists study Müllerian mimicry to understand how predators learn to avoid multiple unpalatable species.
