One tactic to help bee populations stay healthy is raising hygienic bees. Hygienic bees contribute to overall disease resistance by uncapping cells with diseased larvae and removing the diseased larvae. Uncapping (u) is a recessive trait and removal (r) is a recessive trait. A cross between a hygienic queen (uurr) and a unhygienic drone (UR) yields unhygienic bees. Remember males bees are haploid. With what could you cross the offspring to produce hygienic workers (females) in the F2 generation

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
