Answer:
(1). Full brother share:
Full brother share exists when there is no descendants of the diseased person( male or female) and Parents exit.
case 1: Full brother is one (no sisters or brothers)
then his share shall be =1
case 2: if Full Brother and Sister exist
then full brother and Full Sister: 1:2

(2). Daughter share:
Daughter can inherit from the parents
case:1 if she is only one (no brother or sisters)
then her share is =1/2
case 2: if there are more than 2 daughters and no Son
daughters= 2/3
Daughter's son's and daughter's daughters can not inherent from the her mother's parents.

so according to the rule:
A Muslim dies leaving a daughter’s son and a full brother
Full brother shall share will be =1
no share shall be daughter's son.

if i am wrong please correct me.
