“…Genetic selection of animals, which leads to the birth of increasing numbers of animals with desirable traits, and most importantly without genetic defects, is of great importance (Trukhachev et al, 2017). Chromosomal anomalies can be generated during meiotic and mitotic cell division and cellular mechanisms such as meiotic recombination, replication or repair of DNA damage (Catteeuw, 2018; Holecková et al, 2021; Jayashree et al, 2020). They are usually lethalin early embryogenesis, but can also lead to intrauterine death of the foetus, developmental defects and slowed development, resulting in economic losses for the breeder (Catteeuw, 2018; Holecková et al, 2021).…”

Damage to genetic material and errors in the functioning of cellular mechanisms disturb genome stability and integrity. Assessment of genomic stability in animals is a very important aspect of breeding work. Unfortunately, harmful instabilities affect the functioning, health and reproductive processes of animals. Obtaining healthy calves is a priority, whatever methods of reproductive biotechnology are applied. The aim of the study was to assess the genomic stability of calves obtained from artificial insemination and OPU/IVP in vitro fertilization. The genomic stability of the calves was evaluated using the comet, sister chromatid exchange, and fragile sites assays. Damage to the genetic material of calves obtained by two reproductive biotechnologies was identified. Identification of instability in animals can be a valuable tool in breeding work and accelerate breeding progress.
