The meiotic behavior of an inversion in Caenorhabditis elegans. [PDF]
Abstract The rearrangement hIn1(I) was isolated as a crossover suppressor for the right end of linkage group (LG) I. By inducing genetic markers on this crossover suppressor and establishing the gene order in the homozygote, hIn1(I) was demonstrated to be the first genetically proven inversion in Caenorhabditis elegans.

Meiosis-specific loading of the centromere-specific histone CENH3 in Arabidopsis thaliana. [PDF]
Centromere behavior is specialized in meiosis I, so that sister chromatids of homologous chromosomes are pulled toward the same side of the spindle (through kinetochore mono-orientation) and chromosome number is reduced.

Sexual breeding at the tetraploid level is a promising strategy for rootstock breeding in citrus. Due to the interspecific origin of most of the conventional diploid citrus rootstocks that produced the tetraploid germplasm, the optimization of this ...

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]
Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

Meiotic behavior and pollen fertility in triploid and tetraploid natural populations of Campuloclinium macrocephalum (Eupatorieae, Asteraceae) [PDF]
Campuloclinium macrocephalum DC. is a perennial herb widely distributed in the New World and introduced in South Africa, where it is commonly called ‘‘pompom weed’’.

Triticale (X Triticosecale Wittmack) is a good cereal for production of flour and feed. A segregating population of triticale was developed from a male-sterile (MS) plant. To determine whether this new source of male sterility in triticale is appropriate

A sex-ratio meiotic drive system in Drosophila simulans. II: an X-linked distorter. [PDF]
The evolution of heteromorphic sex chromosomes creates a genetic condition favoring the invasion of sex-ratio meiotic drive elements, resulting in the biased transmission of one sex chromosome over the other, in violation of Mendel's first law.
