Most of snakes exhibit a ZZ/ZW sex chromosome system, with different stages of degeneration. However, undifferentiated sex chromosomes and unique Y sex-linked markers, suggest that an XY system has also evolved in ancestral lineages.

What does OD mean in ball pythons?
The Orange Dream Morph in Ball Pythons.
What genes are dominant in ball pythons?
Examples of Dominant Ball Python morphs include the Spider gene and the Pinstripe gene. Both of these mutations can be bred together to make a homozygous super form that is no different visually than the single gene Spider or Pinstripe but when used in breeding will make a 100% yield of visual offspring.
How many chromosomes does an anaconda have?
3. Results. The Amazonian red-tailed boa (Boa constrictor), the dark-spotted anaconda (Eunectes deschauenseei) and the North rainbow boa (Epicrates maurus) have 2n = 36 chromosomes (16 macro + 20 microchromosomes), similar to other karyotyped Boa, Eunectes, and Epicrates species .
Can snakes reproduce asexually?
Asexual reproduction usually happens when a female is unable to find a male in the wild to fertilize her eggs. Scientists once believed this type of reproduction was rare, but there is more and more evidence to show that there are more snake species that reproduce asexually than they expected.
