Figure 2. The frequency distribution of parental height differences (a) and the relative likelihood of pairing (b).

Figure 2

Parental Height Differences (PHD) in bins of 5 cm. The relative likelihood of pairing in these bins is the frequency of the bins in the original population divided by the median (±97.5% upper/lower limit) occurrences of that bin in the 10,000 samples of random mating (see text). A number greater (lower) than one (solid horizontal line) means that the PHD bin is more (less) likely to occur in the original population than expected by random mating.
