Paula was tiny so Tiger obviously takes after her mum. I also see Paula's features in Tiger, despite everyone saying she is her dads double. In fact I have never been able to see any resemblance with her other girls.
Bob G is very tall so his girls have his height.
I could never much of a resemblance between Paula and Peaches. I always thought she was the child that bore the strongest resemblance to Bob,
especially in her teenage years. In later years she definitely had some work done and lost a lot of weight. I remember speculation of an ED but that was before her death and the revelation that she had been battling a heroin addiction.
