Segregation of the isozymes of flax genotrophs.

The segregation of isozymes of peroxidase and acid phosphatase in progenies of crosses between large (L) and small (S and L6) flax genotrophs has been determined. The peroxidase isozymes segregated as expected on a simple Mendelian model with a dominant and a recessive allele and with the L genotroph being a homozygous dominant. All the peroxidase isozymes which differed segregated together, so the isozymes are controlled by either a single locus or closely linked loci. The acid phosphatase isozymes in the F1 were all L type, but the segregations observed in the F2 were not always consistent with a simple Mendelian model.
