Fig. 7.9 Trial-to-trial variation in mean number of unique alleles retained by different numbers
of founders is reduced by increasing the number of replicate loci. Trial results marked “B”
are the same as shown in Fig. 7.5 (see discussion of that fi gure for details on the analysis).
Trial results marked “C” were generated in exactly the same manner, except that in the case
of the B trials only one locus was used, whereas 20 copies of that one locus were analyzed in
each of the C trials. Note that increasing the number of one type of locus reduces the amount
of variation among means of replicate trials. FOUNDERS = number of founders; TOTAL =
total number of unique alleles available in the source population (B trials, a maximum of 10
available; C trials, a maximum of 200 unique alleles); PERCENT = percentage of the total
number of unique alleles available retained in a founding population. The percentage retained
increases as the number of founders increases.

Fig. 7.10 In parallel with results shown in Fig. 7.9, variation in estimates of heterozygosity
decreases when duplicate loci are added to the analyses (B, one locus only; C, 20 duplicates
of the single locus in B trials are analysed). See Fig. 7.9 and text for further details.
