UNIPARENTAL INHERITANCE IN <i>CHLAMYDOMONAS EUGAMETOS</i> (CHLOROPHYCEAE)^1,²

Abstract

SUMMARY The gene sr‐2 conferring resistance to 500 μ/ml streplomycin exhibits uniparental inheritance in Chlamydomonas eugametos Moewus. The mutation to neamine dependence (nd) is probably of the same type. All meiotic progeny from crosses involving these mutant genes have the phenotype of the historically designated male parent. Unlike C. reinhardtii Dang., no exceptional zygotes have been observed.
