This effect is mirrored in humans, where mutations in the WNT4 gene has been observed in MRKH syndrome patients, who display hyperandrogenism. Mutations in WNT4 gene are not always present in individuals with Müllerian anomalies or MRKH syndrome, but the WNT4 gene is the only gene that has been clearly implicated in MRKH.
Illustration of chromosome crossover during genetic recombination. In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process which, in the absence of recombination (especially in an asexual population), results in an accumulation of irreversible deleterious mutations.
The assumption of a fixed number n to be attacked is a useful first step, but unlikely to perfectly reflect the effect of predators' memories. [5] Müller also effectively assumed a step function, when a gradual change (a functional response [11]) is more plausible. [10]
The condition also occurs in XY males, as they suffer from the effects of low cortisol and salt-wasting, not virilization. Persistent Müllerian duct syndrome – A rare type of pseudohermaphroditism that occurs in 46 XY males, caused by either a mutation in the Müllerian inhibiting substance (MIS) gene, on 19p13, or its type II receptor ...
Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane-bound organelles. The formation of cellular compartments is called compartmentalization.
Compartment boundaries establish these organizing centers [5] [7] by providing the source of morphogens [9] that are responsible for the positional information required for development and regeneration. [9] [10] The inability of cell competition to occur across the boundary, indicates that each compartment serves as an autonomous unit of growth.
Müllerian agenesis, also known as Müllerian aplasia, vaginal agenesis, or Mayer–Rokitansky–Küster–Hauser syndrome (MRKH syndrome), is a congenital malformation characterized by a failure of the Müllerian ducts to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion.
Sinus tubercle (also known as sinual tubercle [1] or Müllerian eminence) is the proliferation of endoderm induced by the paramesonephric ducts.It is located in the developing fetus between the orifices of the mesonephric ducts on the urogenital sinus. [1]
