Baer, B. The shape and course of spermducts appear normal. Galizia, C. The processing of fem and Am-dsx transcripts in the response to the knockdowns of the csd and the fem gene induced by RNAi. Ovary activation and insemination All females were dissected under a microscope. No significant linkage disequilibrium between loci was detected.
L1 and L5 are 1 st and 5 th instar larvae, P2 are pupae at medium stage. The diploid queen has 32 chromosomes and the haploid drones have 16 chromosomes. Michael G. These data clearly suggest that a drone-produced attractive odour substance may be involved in the formation of drone congregations.
Our injections of dsRNAs targeted at repressing the function of the GB and GB genes produced individuals with unchanged gonad development Table 1Figure 2D—2Gsuggesting that neither gene is required for sex determination. Some species mate at the female emergence site e.
