They're unisexual, and their sex life is singularly boring, if you'll pardon the expression.

These results are compared with evo-devo theories on flower bisexuality, as derived from unisexual ancestors.

Diploid AD hybrids are derived either from a-alpha mating or from unisexual mating between haploid cells.

The unisexual (male and female) flowers, may be on the same or on different plants.

Here there is not, as in the Catasetum, any external change visible in the respective unisexual and bisexual flowers.

These offspring maintain morphological traits of their allotriploid maternal and form an allotetraploid unisexual clone by gynogenetic reproduction mode.

The flowers, which are produced in April, are small and yellow, unisexual, or each sex on a distinct plant.

If you can advance good evidence showing that bisexual plants are more variable than unisexual, it will be interesting.

How unisexual animals eliminate deleterious mutations to avoid dead ends is one of the most interesting puzzles in evolutionary genetics.

Dr. George W. Field, an expert authority, says the oysters of Europe are unisexual, but in America, they are double-sexed.

The starting-point of the class, however, and the position within it of apetalous families with frequently unisexual flowers, have provoked much discussion.

Structurally hermaphrodite flowers become unisexual by suppression, or are rendered incomplete by the non-development of one or more of their floral whorls.

In plants, likewise, a long and finely graduated series of transitions leads from bisexual to unisexual blossoms; and so in various other respects.

Recently, polyploid gibel carp has been revealed to possess coexisting dual modes of unisexual gynogenesis and sexual reproduction and to have numerous various clones.
