Genomic evidence for hybridization and introgression between blue peafowl and endangered green peafowl and molecular foundation of leucistic plumage of blue peafowl.

ABSTRACT:

Introduction

The blue peafowl (Pavo cristatus) and the green peafowl (Pavo muticus) have garnered significant public affection due to their stunning appearance, although the green peafowl is currently endangered. The causative mutation that causes the leucistic plumage of the blue peafowl (also called white peafowl) remains unknown.

Results

In this study, we generated a chromosome-level reference genome of the blue peafowl with a contig N50 of 30.6 Mb, including the autosomes, Z and W sex chromosomes, and a complete mitochondria DNA sequence. Data from 77 peafowl whole genomes, 76 peafowl mitochondrial genomes, and 33 peafowl W chromosomes genomes provided the first substantial genetic evidence for recent hybridization between green peafowls and blue peafowls. We found 3 hyb
