    Does the average of the autosomal results of two parents equal the child's?

    For example, if I took the average between my autosomal results and my fiancee's would that equate (approximately) to what our child would receive?

    It should, but sometimes doesn't. Especially if there's some admixture confusing the software. My family's doesn't wind up averaging out (I'm almost identical to my dad and my mom is identical to her mom and even though everyone is related to one another, there's a 4-5% swing from one person to the next in components).
