Only one F1 fly is shown in A) and another in B) (F1 progeny are in pink boxes). M (in red) denotes a phenotypically detectable, dominant mutation; m (in red) denotes a recessive mutation.

You can expect: (PLEASE SELECT ONE ANSWER), using pink box from both A and B

a) All of the F1 progeny will carry mutations that affect eye color (the phenotype you are following) b) Each F1 fly will likely carry a unique mutation(s) distinguishing it from other F1 flies c) All F1 flies with mutations will carry dominant mutations d) Only male F1 flies will carry mutations A)", E: ) +++la -+IWT :F1 xL301 ttt^-+ | F1 0+ B ? A-10L
