what is the meaning of half brother or sister
Sibling Half-siblings are people who share one parent but not both. They may share the same mother but different fathers (in which case they are known as uterine siblings or maternal half-brothers/half-sisters), or they may have the same father but different mothers (in which case, they are known as agnate siblings or paternal half-brothers/half-sisters. In law, the term consanguine is used in place of agnate). They share only one parent instead of two as full siblings do and are on average 25% related.[3]
Sister Wives Meri, Robyn, and Christine were all raised in polygamist families, but Janelle was not. Although Christine's mother left the faith she still supports them. Months before the marriage of Janelle and Kody, however, Janelle's mother entered into a polygamist marriage with Kody's father.[5] The Brown family belonged to the Apostolic United Brethren (AUB). For years before the series, the family kept their polygamist lifestyle what they called a "quasi-secret".[10]
