Interchromosomal connections and metaphase 1 clumping in meiosis of two ,i>Capsicum Linn. species in Nigeria

Abstract

The occurrence of interchromosomal connections in two species of Capsicum; Capsicum annuum L. and Capsicum frutescence L., from Nigeria is reported. Clumping of metaphase 1 chromosomes is also reported for these two species. The degrees of incidence of the interchromosomal connections and metaphase 1 chromosomes clumping have been determined. The probable relationship between the chromosomal connections and metaphase 1 clumping and the possibility of their being a useful ecological adaptation are discussed.
