Body axis development is determined by a MATERNAL EFFECT gene in Drosophila. A dominant Bicoid gene allele is required to set up the correct axis development in flies. The bb (two loss of function alleles) genotype is LETHAL in this MATERNAL EFFECT gene. A female Drosophila had all dead offspring, caused by Bicoid loss of function. What is this female fly’s GENOTYPE?
