A true hermaghrodite has the gonads of both sexes, either
as a separate ovary and testis, or combined into an Ovotestis.

A Eseudohermaghrodite has the gonads of one sex only, but
Possesses reproductive Organs with some of the characteristics
of the opposite Sex. Such an individual is classed as a male
or female on the type of gonad bpresent. Thus a male pseudo-
hermaphrodite has largely female external genitalia, but the
gonadal tissue is testicular.

A chimera is an individual with cell lines derived from
different genotypes, for eéxample by fusion of early cleavage
stages or by an exchange of cells in utero.

A mosaic is an individual with different cell lines
which have arisen in development, for eéxample by mitotic
nondysjunction.

Often the words chimera ang mosaic are used interchange—
ably since frequently the origin of the different cell lines

are unknown.
