Maternal effect genes
mRNA distributions
A Drosophila oocyte is a polarized cell. The future anterior-posterior axis of the fly is established by mRNA molecules that are differentially localized within the oocyte.
In cases of maternal effect, the transmission pattern of the alleles is the same as in standard Mendelian genetics but the action of the gene occurs a generation later.
