# The genome sequence of the Common Pochard, Aythya ferina (Linnaeus, 1758)

## TL;DR

This paper provides the genome sequence of the Common Pochard, a bird species, including detailed assembly of its chromosomes and mitochondrial DNA.

## Contribution

The study presents a high-quality genome assembly of Aythya ferina, including chromosomal pseudomolecules and mitochondrial genome.

## Key findings

- The genome assembly includes two haplotypes with lengths of 1,252.30 and 1,103.59 megabases.
- Haplotype 1 is scaffolded into 41 chromosomal pseudomolecules, including W and Z sex chromosomes.
- The mitochondrial genome is assembled with a length of 16.6 kilobases.

## Abstract

We present a genome assembly from a female specimen of
Aythya ferina (Common Pochard; Chordata; Aves; Anseriformes; Anatidae). The assembly contains two haplotypes with total lengths of 1,252.30 megabases and 1,103.59 megabases. Most of haplotype 1 (92.13%) is scaffolded into 41 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 16.6 kilobases.
