Australian experts state they usually have cracked the code which explains why reptiles alter sex underneath the stress of extreme temperatures.
The proposed model could help manage biodiversity also as reptiles come under great pressure from weather modification.

” The Australian dragon lizard has latin dating intercourse chromosomes comparable to birds that determine sex at normal conditions. But at high temperatures, embryos with male intercourse chromosomes reverse sex and hatch as females,” stated research writer, CSIRO evolutionary geneticist Clare Holleley.
Researchers are involved that increasing conditions could impact the intercourse ratio of types just like the beardie.

Dr Holleley said that of these species “survival under climate modification comes down to: move, adjust or die”.
It has been recognized for many time that heat extremes can trigger intercourse reversal in reptiles.
In bearded dragons intercourse reversal begins to take place at low percentages in male eggs when they’re incubated at 32 levels. […]
