Different Frequency in the Recovery of Crossover Products from Male and Female Gametes of Plants Hypoploid for B-a Translocations in Maize

D S Robertson. Genetics. 1984 May.

Abstract

The percentage of crossovers is consistently higher in plants hypoploid for six B-A translocations when crossed as males than when crossed as females; in most instances, this excess of male crossing over exceeds that found in control crosses (involving normal chromosomes). Thus, there seems to be something about the hypoploid condition that is responsible for the higher percentage of male crossovers. Several explanations for this "hypoploid effect" are possible, but none has been demonstrated to be responsible for the phenomenon.
