- A series of 15 samples of house sparrows taken in the East Midlands of England were screened for 14 variable and 9 invariable enzyme loci. The gene frequency data were analysed both for heterozygosity and genetic identity using Nei's and Roger's statistics. There is a cline in heterozygosity northwards across the region, and populations are closely similar. The differentiation observed is very close to that expected for a continuously distributed species with a neighbourhood area of 8.9 km2 and effective population size of 999.6.
