Chromosomal abnormalities, meiotic behavior and fertility in domestic animals
Cytogenetic and Genome Research, 2008 Since the advent of the surface microspreading technique for synaptonemal complex analysis, increasing interest in describing the synapsis patterns of chromosome abnormalities associated with fertility of domestic animals has been noticed during the past three decades. In spite of the number of scientific reports describing the occurrence of structural

Meiotic chromosome abnormalities in human spermatogenesis
Reproductive Toxicology, 2006The last few years have witnessed an explosion in the information about chromosome abnormalities in human sperm and the meiotic events that predispose to these abnormalities. We have determined that all chromosomes are susceptible to nondisjunction, but chromosomes 21 and 22 and, especially, the sex chromosomes have an increased frequency of aneuploidy.

Meiotic abnormalities in Saccharum spontaneum
Euphytica, 1975Meiosis was studied in several clones of Saccharum spontaneum with chromosome numbers ranging from 2n=40 to 2n=126. Abnormalities recorded include occurrence of univalents, pseudo bivalents, multivalents, heteromorphic or unequal bivalents, chromosome mosaicism, secondary association of bivalents, and complement fractionation.

LSD in Mice: Abnormalities in Meiotic Chromosomes
Science, 1968Meiotic chromosomes of six mice injected with high doses of lysergic acid diethylamide (LSD-25) and of six controls were studied. Several breaks, gaps, and unidentifiable fragments were found in the treated but, with a few exceptions, not in the control animals.
