Drosophila buzzatii is a fruit fly that feeds on the rotting fruits of cacti in Australia. Timothy Prout and Stuart Barker calculated the heritabilities of body size, as measured by thorax length, for a natural population of D. buzzatii raised in the wild and for a population of D. buzzatii collected in the wild but raised in the laboratory (T. Prout and J. S. F. Barker. 1989. Genetics 123:803–813). They found the following heritabilities: Population Heritability of body size (± standard error) Wild population 0.0595 ± 0.0123 Laboratory-reared population 0.3770 ± 0.0203 Why do you think that the heritability measured in the laboratory-reared population is higher than that measured in the natural population raised in the wild?
