Synapomorphies uniting Canrightia with the crown group are sessile flowers, inferior ovary, one perianth whorl, and orthotropous ovule, while the crown group is further united by
unisexual flowers, one stamen, and one carpel.
Histocompatibility analysis of clonal diversity in
unisexual hybrids of the killifishes Fundulus heteroclitus and Fundulus diaphanus.
The
unisexual, internally fertilised, live-bearing Amazon molly-fish Poecilia formosa (Girard, 1859) from northeast Mexico and southern Texas is a well-known gynogen.
Changes in prevalence and intensity of larvae in an opportunistically collected sample of faeces should reflect changes in the proportion of fawns in the population, as well as weather-related transmission rates determining the frequency of sterile
unisexual infections.
(iv) Pollination of
Unisexual and Aggregated Flowers.
Unisexual (all female) Ambystoma salamanders produce offspring using a special form of reproduction known as kleptogenesis, in which insemination by a sexual male species is necessary to trigger egg development, but the male's genome is often not incorporated into the zygote.
Deceitful pollination by anther-mimicking stigma had been known earlier only in cases of species with
unisexual flowers.
Male phase of coenanthia lasted an average of 38 days in Dorstenia arifolia (12 days in
unisexual male coenanthia) and 19 days in D.
Sex ratio and
unisexual sterility in hybrid animals.
