Summary: Fluorescence in situ hybridization analysis was performed to investigate the numerical chromosomal abnormalities in the sperm of Robertsonian translocation carriers. The results showed that both the translocated and nontranslocated chromosomes were affected, with the translocated chromosomes being more affected. This study provides important insights into the impact of translocation-derived chromosome disturbances on meiotic segregation.

Summary: This study focuses on the issue of sub-fertility in breeding bulls in the cattle industry and proposes an RT screening program and estimates the economic impact. The results show that using RT screening methods can reduce economic losses per bull over six years, which is also important for the overall cost and environmental protection in the cattle industry.

Summary: The study used FISH with bovine WCP and BAC probes to analyze chromosome rearrangements and gametic segregation in brown brocket deer, finding a slight to moderate increase in the rates of unbalanced meiotic segregation products in individuals heterozygous for RT and RT/PAIs, but without statistical significance.

Summary: The study aimed to visualize sex chromosomes in domestic cat sperm using the FISH technique, successfully showing the presence of X and Y chromosomes. This technique may be useful for detecting chromosomal abnormalities in feline sperm.

Summary: The study investigated the effects of non-Robertsonian translocation with chromosome fusion (N-RBCF) on preimplantation embryos. Results showed that blastocysts from N-RBCF carriers with Y fusion had a low number of unbalanced translocations, while the risk of unbalanced translocation in autosomal N-RBCF was higher than in Robertsonian translocation, especially in male carriers.

Summary: This study investigates a new method called APCAD for reliably detecting mosaic aneuploidy in preimplantation embryos. By evaluating maternal contribution, the method can distinguish mosaic and complete aneuploidy and determine the parent of origin for the chromosomal anomalies.

Summary: Our study demonstrated that meiotic segregation heterogeneity of trivalent structure is associated with the carrier's gender and translocation type, and it is independent of carrier's age. ICE phenomenon exists during meiosis and then increases the frequencies of additional chromosome abnormalities.

Summary: Our study shows that only the rye-derived centromere part in the wheat-rye 1BL/1RS translocation chromosome incorporates wheat CENH3, supporting the idea that one centromere part undergoes inactivation in a translocated chromosome to maintain chromosome stability.

Summary: This study investigated the preimplantation genetic testing outcomes of 300 couples who were carriers of structural rearrangements. The results showed that the type of rearrangement, female age, and carrier's sex had significant impacts on the proportion of transferable embryos, but there was little or no evidence for an interchromosomal effect (ICE). This study provides a statistical model for investigating ICE and improves personalized reproductive genetics assessment for structural rearrangement carriers.

Summary: Agropyron cristatum, an important wild relative of wheat, may carry genes for increased grain weight and width on its 6P chromosome. The development of Robertsonian translocation lines could promote the utilization of the 6P chromosome of Agropyron cristatum in wheat improvement.

Summary: The study found that reciprocal translocation carriers have a higher risk of unbalanced rearrangement, while embryonic chromosome abnormalities of inversion carriers mainly come from de novo variations. This study is the first to specifically compare three different PGT-SRs using the NGS method and evaluate their reproductive outcomes.

Summary: In addition to companion animals and laboratory species, approximately 270 carnivore species play vital ecological roles in various ecosystems. However, the majority of these species are now threatened or endangered in the wild due to human activities. Protecting their natural habitats is crucial, but understanding carnivore reproduction, particularly in terms of sperm, oocyte, and embryo biology, is equally important for maintaining sustainable populations and conservation efforts. This review aims to provide the latest knowledge on the biology of sperm cells, oocytes, and early embryos across all carnivore families, highlighting the need for further research and the development of conservation strategies.

Summary: The study evaluated the effectiveness of antifreeze proteins in fish sperm cryopreservation and found that antifreeze proteins type I and III significantly preserved sperm motility and viability. Future studies should focus on the combined effect of heterogeneous sources.
