Fig. 2

Representative gel of the polymorphism pattern resulting from the restriction with PvuIIof amplified samples for the estrogen receptor alpha. Samples with one band only indicate a wild profile (~ 1300 pb, eg., lane 12), whereas samples with three bands (~ 1300, ~ 900, and ~400pb, eg., lanes 3 and 5) and with two bands (~ 900 and ~400pb, eg., lanes 7 and 9) indicate the heterozygous and homozygous profiles for mutation, respectively. The arrows point to the migration of each of the expected fragments
