Your brother no longer has the right to inherit as a descendant. The adoption removes the right to claim an inheritance as a son once the adoption process is complete, provided the natural parent did not die before the adoption. There are special rules if the adopting parent is a descendant of the natural parent. However, the natural father can make a bequest to anyone under a Will, including your brother. If your brother was named in his biological father's Will then he could claim his share of the estate as granted by the terms of the Will.
