Evolution's Rainbow: Diversity, Gender, and Sexuality in ...
Among Talpa occidentalis—another burrowing mammal, an old world mole from
the Iberian peninsula—all females have ovotestes, gonads containing both
ovarian and testicular tissue.16 The ovotestes occur at the site in the body where
...

Genetics of Sex Determination
Bilateral ovotestes are rare.62 This is in contrast to the gonads of XX
hermaphrodites where the majority have an ovotestis and contralateral ovary or
bilateral ovotestes. Therefore, the gonads in XY hermaphrodites are more
masculine relative ...

Feminization in Common Terns (Sterna Hirunda): Relationship ...
Concern about skewed sex ratios and female-female pairings among endangered roseate terns (Sterna dougallii) on Bird Island in Buzzards Bay, Massachusetts prompted studies with common terns from the same site as a surrogate species.

Isozymes V3: Developmental Biology
in ova removed from the ovotestes. All tissues of R.marmoratus also contained
esterases capable of hydrolyzing d-NA. However, the number of detectable
isozymes (five) was less than that hydrolyzing c—NB, as was the number of
different ...

The Genetics and Biology of Sex Determination
In mammals, the occurrence of ovotestes is rare. Development of ovaries or
testes is strongly canalized. Once the balance is shifted in a given direction, the
entire cell population in the gonad is usually recruited to whichever program is ...

Sex Determination, Differentiation and Intersexuality in ...
The delayed onset of testicular differentiation during development of XY
ovotestes probably permits switching on of the ovarian differentiation pathway,
thereby producing XY ovotestes (Merchant-Larios & Taketo. 1991). Also to be
considered, ...

Emery and Rimoin's Principles and Practice of Medical Genetics
In 80% of his cases, the testicular and ovarian components of ovotestes were
juxtaposed end to end (Figure 88-12) (227), seemingly different from the recent
experience of Wiersma. Van Niekerk collected cases from the region surrounding
...

Comprehensive Gynecology: Expert Consult - Online
Ovotestes Ovotestes are present in individuals with ovaries that have an SRY
antigen present. The majority are true hermaphrodites (quite rare). The degree to
which Mu ̈llerian and mesonephric development occurs depends on the
amount ...

Body Heat: Temperature and Life on Earth
Whether the ovotestes go one way or the other depends upon the presence or
absence of a hormone that is produced only by the Y chromosome. If this
hormone is present, then the ovotestes will develop into testes; if not, they will
develop ...
