Editing Australian zebra finch (section)

====Inbreeding====
[[Inbreeding]] causes early death ([[inbreeding depression]]) in the zebra finch, although it does not seem to affect fertility. Embryos have a much lower survival rate, with a study finding fertile eggs from [[sibling|sibling pairs]] had only about a 25% survival rate, compared to about 41% for unrelated pairs. This early difference in survival eventually becomes null after fledging, with about equal survival rates for offspring from both sibling and unrelated pairs.<ref name="pmid22643890">{{cite journal |vauthors=Hemmings NL, Slate J, Birkhead TR |title=Inbreeding causes early death in a passerine bird |journal=Nature Communications |volume=3 |pages=863 |year=2012 |pmid=22643890 |doi=10.1038/ncomms1870 |bibcode=2012NatCo...3..863H |doi-access=free }}</ref> Inbreeding depression mostly arises due to the expression of deleterious recessive alleles.<ref name="pmid19834483">{{cite journal |vauthors=Charlesworth D, Willis JH |title=The genetics of inbreeding depression |journal=Nature Reviews Genetics |volume=10 |issue=11 |pages=783–96 |year=2009 |pmid=19834483 |doi=10.1038/nrg2664 |s2cid=771357 }}</ref>
