The overall compaction rate of DNA molecules in mitotic chromosomes of dioecious Coccinia indica and Trichosanthes dioica has been measured in the present investigation. The data indicates that the average packing ratio differs significantly in relation to sex and the compaction rate is comparatively high in male plant of these dioecious species. Based on the estimates of this packing ratio, a theoretical proposition on the possible evolution of sex chromosomes in relation to dioecy has been explained.
