Patterns of paternity: insights into mating competition and gene flow in a recovering population of humpback whales.

Variation in reproductive success is a fundamental prerequisite for sexual selection to act upon a trait. Assessing such variation is crucial in understanding a species' mating system and offers insights into population growth. Parentage analyses in cetaceans are rare, and the underlying forces of sexual selection acting on their mating behaviours remain poorly understood.

Objective: To investigate the clinical features and genetic variants associated with Multiple mitochondrial dysfunction syndrome (MMDS) type 3 in two children.
Methods: Two children diagnosed with MMDS type 3 at Zhuhai Maternal and Child Health Care Hospital in January 2021 were selected for this study. A retrospective analysis of their clinical data was carried out.
Unexpected recombination at the polled locus in a horned Holstein calf from the mating of a homozygous polled sire and a heterozygous polled cow.
Anim Genet

Institute of Veterinary Medicine, University of Göttingen, Göttingen, Germany.
In this study, I report an unexpected case of a Holstein calf that developed horns even though the sire was homozygous and the dam was heterozygous for polledness. After verifying and confirming the correct parentage, the parents and offspring were genotyped with the Illumina EuroG_MD BeadChip and the SNPs in the polled region on chromosome 1 were evaluated. In addition, the father was sequenced with next generation sequencing to identify possible, previously unknown variants.

PLoS One
January 2025
Department of Global Public Health and Primary Care, Faculty of Medicine, University of Bergen, Bergen, Norway.
Background: Studies have reported that pregnancies conceived by fathers with modifiable cardiovascular risk factors are at higher risk of ending in losses compared to those without such risk factors. Our objective was to examine the association between paternal family history _a non-modifiable risk factor_ of premature atherosclerotic disease and perinatal death.
Methods: This is a population-based cohort study.
Investigating the Risk Factors Associated with Type 1 Diabetes (T1D) in the South of Iran: A Casecontrol Study.
Curr Diabetes Rev
January 2025
Assistant Professor, Department of Public Health, School of Health, Jiroft University of Medical Sciences, Jiroft, Iran.
Background: Type 1 diabetes (T1D) is an autoimmune disorder characterized by a complex interplay of genetic and environmental factors.
Aim: The objective of this study was to identify the risk factors associated with T1D in the southern region of Iran during the year 2022.
Methods: This research employed a case-control design involving two groups (79 individuals in each group) of healthy children and adolescents diagnosed with T1D.
