Multiple Choice
How do genetic mosaics help determine the focus of action of a gene?
A) Mosaics ae composed of cells with different genotypes so some genes may be active in some cells and not others.
B) Mosaics are created by mating flies are homozygous recessive for two different genes and the effects of the double miutations on the morphololgy of the progeny are studied.
C) Mosaics are created by mating two flies that carry homozygous gain-of-function muttions in different genes and the effects of the mutations on the morphology studied.
D) Mosaics are created by the Cre-loc system which allows for the deletion of specific genes at controlled stages of development.
