Angolan colobus monkey (Colobus angolensis)

Infant Angolan colobus monkeys are born solid white. They will develop the characterstic black coloration of the adult colobus around 3 months old. Read more about angolan colobus monkeys on the Atlanta Zoo's website.

Draft

The chromosome-length genome assembly is based on the draft assembly Cang.pa_1.0 (GCA_000951035.1), credited below.

Unpublished. https://www.ncbi.nlm.nih.gov/nuccore/JYKR00000000.1/.

Method

3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018). See Methods for more information.

Hi-C sample

The muscle sample for in situ Hi-C preparation was donated by a female individual, and obtained from San Antonio Zoo.

Hi-C Contact maps

Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). (Please note that the interactive figures are scaled 1:2.) To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018).
