Bearded dragon embryos can use two different sets of genes to become a female lizard--one activated by the sex chromosomes and the other activated by high temperatures during development. Sarah ...

Some lizards that begin developing as males will actually hatch as females if the egg is particularly warm – and now we know why. The heat triggers genes that override chromosomal sex determination.

Two independent research teams have unveiled near-complete reference genomes of the central bearded dragon, a reptile with the rare ability to change sex depending on both chromosomes and nest ...

Some genetically male Australian bearded dragons are growing up as fully functional females in the wild — the first reptiles confirmed to reverse sex under natural conditions. Earlier research had ...

The preservation of genetic variation is of special importance in captive breeding populations, which provide a reservoir of genetic material to be used to re-establish or reinforce populations in the ...

Spanish scientists learned that warmer conditions scramble the DNA inheritance patterns in lizards that live in Madagascar and Australia, which makes it harder for these animals to pass healthy genes ...
