Popsicle Stick Question for Tuesday

Filed under: Uncategorized — admin @ 11:46 am

In lecture Pat pointed out that an X chromosome balancer does not carry a lethal mutation and instead carries a recessive female sterile mutation (in addition to inversions and viable dominant visible mutation).  Describe how a lethal mutation on the X chromosome can be stably carried in a stock with such a balancer and explain why it won’t work if the balancer has a lethal mutation.  Hint – just draw it out and remember that males are XY.
