The population were allowed to breed freely for four months, when the
frequencies of PP in 300 sample chromosomes were determined in each line. A
new cycle was started in each case from 20 flies. The process was repeated

Second chromosomes from each of 10 sons were tested for homozygous viability
in the usual way. Among the 1,900 recombination chromosomes, 77 were lethal
when homozygous (4.0%). These were much more numerous than expected ...

The viabilities of Drosophila, homozygous for certain quasi-normal second
chromosomes, are improved by random mutations (shown to be of lowered
homozygous viability in Mukai 's experiments) if these are restricted to one
homologue.
