B chromosomes of maize (Zea mays L.) are positioned nonrandomly within sperm nuclei.

2001-02-01

Abstract excerpt

We used fluorescence in situ hybridization to identify and map the position of B chromosomes (supernumerary chromosomes) within maize sperm cells. Observations on over 1,000 sperm cells from several genotypes show that, on average, the B chromosomes are positioned in the tip one-fourth of the sperm nucleus two-thirds of the time. In contrast, the centromeres and knobs of the A chromosomes (the normal set) are not...
