Early genetic selection of Spanish Trotter Horses by new precocity criteria
Ripollés-Lobo, M.; Perdomo-González, D.I.; Gómez, M.D.; Molina Alcalá, Antonio; Valera, Mercedes (Taylor & Francis, 2024)National trotting races held in Spain between 1990–2022 were used to estimate genetic para-meters for 5 precocity criteria: age at first ranked race (AFR), age when the animal reached 50% of ranked races (A50%), age when ... -
Fine-tuning genomic and pedigree inbreeding rates in equine population with a deep and reliable stud book: the case of the Pura Raza Española horse
Perdomo-González, Davinia I.; Laseca, Nora; Demyda-Peyrás, S.; Valera, Mercedes; Cervantes, I.; Molina, Antonio (Springer, 2022)Estimating inbreeding, which is omnipresent and inevitable in livestock populations, is a primary goal for management and animal breeding especially for those interested in mitigating the negative consequences of inbreeding. ... -
Genomic screening of allelic and genotypic transmission ratio distortion in horse
Laseca, Nora; Cánovas, Ángela; Valera, Mercedes; Id-Lahoucine, Samir; Perdomo-González, Davinia I.; Fonseca, Pablo A. S.; Demyda-Peyrás, S.; Molina, Antonio (Public Library os Science, 2023)The phenomenon in which the expected Mendelian inheritance is altered is known as transmission ratio distortion (TRD). The TRD analysis relies on the study of the transmission of one of the two alleles from a heterozygous ... -
Reproductive traits in Pura Raza Española mares manifest inbreeding depression from low levels of homozygosity
Laseca, Nora; Ziadi, Chiraz; Perdomo-González, Davinia I.; Valera, Mercedes; Demyda-Peyrás, S.; Molina, Antonio (Wiley, 2023)Inbreeding depression is a genetic phenomenon associated with the loss of fitness and mean phenotypic performance due to mating between relatives. Historically, inbreeding coefficients have been estimated from pedigree ... -
Screening and detection of chromosomal copy number alterations in the domestic horse using SNP-array genotyping data
Pirosanto, Yamila; Laseca, Nora; Valera, Mercedes; Molina, Antonio; Moreno-Millán, M.; Bugno-Poniewierska, M.; Ross, Pablo; Azor, Pedro; Demyda-Peyrás, S. (Wiley, 2021)Chromosomal abnormalities are a common cause of infertility in horses. However, they are difficult to detect using automated methods. Here, we propose a simple methodology based on single nucleotide polymorphism (SNP)-array ...
