How many chromosomes do bearded dragons have?
The genome of the central bearded dragon, a squamate from the family Agamidae, has recently been sequenced and assembled into 545,310 sequence scaffolds [34]. The dragon has a karyotype consisting of six pairs of macrochromosomes and ten pairs of microchromosomes (including ZZ or ZW sex chromosomes) [35, 36].
Can bearded dragons impregnate themselves?
Yes, even a female bearded dragon that lives alone can lay eggs. This may be because it recently spent time with a male bearded dragon or simply because it is not uncommon for female bearded dragons, and other types of animals, to lay infertile eggs without ever having been with a male.
