F1 hybridization effects on mouse oocytes

This dataset consists of germinal vesicle (GV) and metaphase II (MII) oocytes from B6, D2, and B6xD2 F1 mice. Oocytes from a single mother were pooled as one biological replicate to become one sample. The goal of the study was to explore the genetic effects on oocyte quality, and more specifically, to determine a viable explanation for the hybrid vigor phenotype displayed in F1 mice. This study is the first to combine oocytes of different stages and different genotypes (two parental inbred strains and F1 hybrid) into a single analysis capable of identifying molecular characteristics that distinguish F1 hybrids. Gene expression profiles for germinal vesicle (GV) and metaphase II (MII) oocytes from B6, D2, and B6xD2 F1 mice were compared.
