Abstract
Cytological observations on several populations of Chrysanthemum carinatum revealed the presence of 2 types of plants: those regularly forming 9 bivalents (homozygotes for the standard or the rearranged karyotype) and others showing a multiple of 4 chromosomes along with 7 bivalents (interchange heterozygotes). These 2 chromosomal types were compared with regard to their reproductive potential. The interchange heterozygotes produced more flowers and seed per plant than the homozygotes. The preponderance of interchange heterozygotes in these populations is determined primarily by their superior reproductive fitness.This publication has 1 reference indexed in Scilit:
