Group:

Reptile

Estimated genome size:

10 - 20 cm (total body length)

Size:

10 - 20 cm (total body length)

Distribution:

Endemic to the Republic of South Africa, occurring in Little Namaqualand from Port Nolloth to Clanwilliam.

PromethION Sequencing Report:

Output:

48.66 Gigabases

Approximate N50:

5.93 kilobases

Draft Genome Assembly Statistics:

Genome Length:

1.56 Gigabases

BUSCO completeness score (single and duplicated genes):

98.8% [S: 96.9%, D: 2.0%]

Importance:

It serves as an important model species for studying specific stages of limb development within the genus Scelotes, representing an intermediate limb development stage (forelimb digits = 0; hindlimb digits = 2), and for investigating the genomic evolution of vertebrates. It has a restricted distribution and occurs in distinct habitats and regions, making it an excellent model species for biogeographic and molecular ecology studies.
