Red-tailed phascogale parentage analysis dataset (1000 SNP loci + life history file) and R script for analysis

We present a case of extended sperm storage in a female red-tailed phascogale (Phascogale calura) during a trial reintroduction in 2022. Parentage reported by single nucleotide polymorphism genotyping revealed the father of one litter had died approximately 50 days before the litter was born. The recorded gestation period for red-tailed phascogales is 28-32 days. Our record indicates sperm storage and/or diapause of up to 15-27 days, at least double the previously recorded sperm storage duration in this species.Published in Australian Mammalogy, October 2024.The data and script provided allow replication of the parentage results generated in the R package Sequoia and used in this publication.我们报道了2022年一项试验性再引入项目中，一只雌性红尾袋鼩（red-tailed phascogale，学名*Phascogale calura*）出现延长精子储存的案例。经单核苷酸多态性（single nucleotide polymorphism, SNP）基因分型得到的亲子关系鉴定结果显示，某一窝幼崽的父亲在该窝幼崽出生前约50天便已死亡。已知红尾袋鼩的妊娠期为28~32天，本次记录表明，该个体的精子储存时长（或胚胎滞育时长）可达15~27天，至少为该物种此前记录的精子储存时长的两倍。本研究成果于2024年10月发表于《Australian Mammalogy》（澳大利亚哺乳动物学）期刊。本文提供的数据与脚本可复现本研究中使用R包Sequoia生成的亲子关系鉴定结果。
