I don't believe Motherx had much control over the process apart from selecting or being selected by Fatherx. The reason I think this is that there is not much she can do to effect her chromosome x and thus the appearance of her daughter due to chromosome x.
Were you aware that Dad's also have an x chromosome which they are unable to manually alter?
but succeeding generations which could be picked up by sexual selection by Motherx through Chromosome y
Through chromosome Y? Aren't we talking about daughters? I think a biology lesson is needed here. You see, when the mommy bird really loves the daddy bird...

Female mammals don't inherit anything via their dad's Y chromosome.
