We report a hybrid genome assembly using Nanopore and Illumina reads of a female EYR, the first published genome for the family Petroicidae. This means that almost any gene on the X, even if it is recessive in the female, will be expressed in males.
Whereas nuclear DNA variation in the EYR is structured mainly north to south, its 2 mitochondrial lineages mitolineages occur in contrasting climates in an east-west coast-to-inland direction, with a narrow contact zone between them, despite ongoing male-mediated gene flow [ 1 ].
A sex chromosome is a type of chromosome that participates in sex determination. Accessed date: 18 September
Smit AHubley R. Accumulation of repeats contributed to this: Fast gapped-read alignment with Bowtie 2. Future work should also test whether unlikely but possible neoZ-1A differences between the EYR used for assembly here and EYR used for scaffolding affected the neo-Z assembly.
The effect of background selection against deleterious mutations on weakly selected, linked variants.
You can unsubscribe at any time and we'll never share your details to third parties. Initially, there were many theories as to how exactly X-inactivation influences sex. The inactivated X chromosome remains within a cell as a Barr body.
Regina Bailey. If an X sperm cell fertilizes an egg, the resulting zygote will be XX, or female. Stevens and the Discovery of Sex Determination by Chromosomes". In this process, an X chromosome and a Y chromosome act to determine the sex of offspring, often due to genes located on the Y chromosome that code for maleness.
Characterization of the inferred neo-sex chromosomes in eastern yellow robin. However, the lack of an EYR reference genome containing both sex chromosomes in birds, a female bearing Z and W chromosomes limits efforts to understand the mechanisms of these processes. Alexandra Pavlova.
Using mate-pair data improved the assembly N50 from to kb. J Biogeogr.
