Abstract
Temperature sensitivity of growth and DNA synthesis was tested in merogenotes heterozygous for the dnaA allele. All combinations tested (F dnaA+/dnaA5, F dnaA+/dnaA46, F dnaA+/dnaA204, F dnaA5/dnaA+, F dnaA204/dnaA+) were temperature sensitive. The mutant dnaA allele is thus trans-dominant to the wild type allele.
摘要
在对dnaA等位基因杂合的部分二倍体中测试了生长和DNA合成的温度敏感性。所有测试的组合（F dnaA+/dnaA5、F dnaA+/dnaA46、F dnaA+/dnaA204、F dnaA5/dnaA+、F dnaA204/dnaA+）均对温度敏感。因此，突变的dnaA等位基因对野生型等位基因是反式显性的。
