Bra expansion at different doses of hairy2 Mos.

Embryos were injected into one blastomere at the 4-cell stage and bra expression was analysed at gastrula stage. The results of two to four experiments were collected and represent the percentage of injected embryos that showed an expanded bra domain. The ratio between brackets indicates the number of cases with expanded bra in relation to the total number of injected embryos. Changes observed with control MO might reflect normal asymmetries of the bra domain, since uninjected sibling controls also showed slight asymmetries in a similar proportion.
