If Fatherx does the choosing I didn't think there was much chance of the daughter's appearance improving.

I think that is an incredibly silly thing to think. I'm sure some things like bone structure and symmetry can be inherited from either the paternal or maternal lineage. For example, my daughter looks a lot more like my mother than she looks like my wife's mother.

I get the impression that your thoughts are dealing with present-day people.

I'm getting the impression that you have not thought this through. Was there some obstacle 200,000 years ago to children inheriting traits from both the paternal and maternal line? If not, then why wouldn't the father's choice of partner matter?

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...

ABE:

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

So can you comment on the hypothesis that a bias exists in the process of evolution from MotherOne to Miss World?

Sure. Given a choice a man is unlikely to marry a woman he finds repulsive. Women make similar choices.

However nobody is going to marry someone who looks anything like that doll RAZD showed you.
