Stable maintenance of duplicated chromosomes carrying the mutant pwB gene in Paramecium tetraurelia.

Genetical research - 1 Aug 2001

Matsuda A, Takahashi M

Abstract excerpt

An allele of the behavioural mutant pawn-B96 has been reported as a typical recessive gene but was found to show a peculiar inheritance. When the F2 progeny from crosses between the wild-type and pwB96 were obtained by autogamy, the 1:1 phenotypic segregation ratio was observed as expected. However, two-thirds of the wild-type progeny in the F2 were thought to be heterozygotes because they became mixed progeny of...
