In recent years, extraordinary progress has been made in a broad range of reproductive
technologies, including spermatogonial transplantation in the male. However, effective …

Simple Summary Molecular cytogenetics, and particularly the use of fluorescence in situ
hybridization (FISH), has allowed deeper investigation of the chromosomes of domestic …

The taurine and zebuine cattle breeds comprise the majority of the world cattle population
but their taxonomic status is still controversial. The two forms of cattle are currently classified …

The hormone Insulin-like peptide 3 (INSL3) is a major secretory product of the Leydig cells
from both fetal and adult testes. Consequently, it is a major gender-specific circulating …

Background Recent transcriptomic analysis of the bovine Y chromosome revealed at least
six multi-copy protein coding gene families, including TSPY, HSFY and ZNF280BY, on the …

Multi-copy gene families are especially prevalent in the male-specific region (MSY) of the
mammalian Y chromosome. Copy number variations (CNV) of these Y-linked gene families …

The next generation sequencing has significantly contributed to clarify the genome structure
of many species of zootechnical interest. However, to date, some portions of the genome …

The mammalian Y chromosome gene families in the ampliconic region are expressed
predominantly or exclusively in the testis, and their copy number variations (CNV) are …

Introduction: MicroRNAs (miRNAs) play a crucial role in regulating gene expression during
key developmental processes, including fetal development. Brahman (Bos taurus indicus) …

A heifer co-twin to a bull, in most cases, is a sterile freemartin which needs to be identified
and culled from replacement stock. Various methods are available for the diagnosis of …
