Abstract
A cytological analysis of meiosis was carried out on the heteromorphic red alga Porphyra yezoensis Ueda (Rhodophyta, Bangiales) using color mutants as genetic markers. The conchospore is released from the conchocelis sporophyte while in meiotic prophase. Reduction division occurs during conchosphore germination and is completed at the four-cell conchospore germling stage. The four meiotic products are linearly arranged in the halpoid leafy thallus affording tetrad analysis in genetic studies of P. yezoensis. Using tetrad analysis the distance between the centromere and the loci of both red and green mutants was determined. In addition, four color mutants were assigned to three different linkage groups.
