Over the years, this method has also been utilized for various purposes such as studying evolution understanding the impact of CNV on transcriptome  and isolation of molecular markers . Despite being a popular model for developmental biology and biomedical research, very little is known about its sexual development for review see .
Krueger W, Oliveira K. More top stories. Selection experiment for increased sex bias We have performed a multi-generation selection experiment in order to increase sex bias. In initial experiments, little to no lethality was observed after 30 dpf thus, in experiment 2 counting ceased after 30 dpf for most populations Table S1 and Fig.
Early Cretan history is replete with legends such as those of King MinosTheseus and the Minotaurpassed on orally via poets such as Homer. They descended from earlier reptiliomorph amphibious tetrapods,  which lived on land that was already inhabited by insects and other invertebrates as well as fernsmosses and other plants.

The cold-blooded Australian Central Bearded Dragon is widespread on red sandy areas in the semi-arid regions of eastern Australia. Sambrook J, Russell D. Rearing density is another environmental cue known to influence sex ratio of some fish species such as the American eel .
However, no sex-linked DNA marker was found suggesting that there are no substantial differences between zebrafish male and female genomes. It was found that under hypoxic conditions there was a reduction of estrogen synthesis leading to an increase of androgen to estrogen ratio which favors male development .
In humans, everyone has an X and the presence of Y makes a person genetically male. Segmental copy number variation shapes tissue transcriptomes.
