Influence of genetic compatibility on offspring fitness in the red-backed toadlet

Presented are data from a manipulative study investigating the influence of parental genetic compatibility on offspring viability in the red backed toadlet (Pseudophryne coriacea). The study used artificial fertilisation techniques combined with a cross-classified breeding design (North Carolina type II) to control parentage and partition sources of genetic and phenotypic variance in offspring fitness. The study also tested the influence of parental genetic similarity on offspring viability. Quantitative genetic analysis of the data revealed no significant additive genetic effects (sire effects), but highly significant non-additive genetic effects (sire x dam interaction effects), on fertilisation success, survival during embryonic development, and hatching success. Analysis also revealled significant associations between parental genetic similarity and offspring survival (whereby survival was higher when parents were more related), and significant positive relationships between ferti...本数据集呈现了一项操控性实验的相关数据，该实验以红背锄足蟾（Pseudophryne coriacea）为研究对象，探究亲本遗传相容性对其后代存活力的影响。本研究采用人工授精技术结合交叉分类繁育设计（北卡罗来纳II型），以控制亲本谱系，并解析后代适合度中遗传与表型变异的来源。本研究同时检验了亲本遗传相似度对后代存活力的影响。对数据的数量遗传学分析显示，在受精成功率、胚胎发育存活率及孵化成功率方面，未检测到显著的加性遗传效应（父本效应），但存在极显著的非加性遗传效应（父本×母本互作效应）。分析还发现，亲本遗传相似度与后代存活率间存在显著关联（即亲本亲缘关系越近，后代存活率越高），且在受精相关指标上存在显著正相关关系（原文内容截断）
