Experiments were performed in 110 ISA Brown egg production hens (Gallus gallus), kept from 15 to 26 weeks of age in enriched (furnished) housing technology. The present objective was to investigate the presence of single nucleotide polymorphisms (SNPs) of the ATP2B1 gene and their effects on calcium homeostasis in laying hens. The plasma membrane calcium-transporting ATPase 1 gene (ATP2B1) in hens is located on chromosome 1, region 43 273 706 – 43 305 815 bp. The ATP2B1 gene has 21 exons, and in this study three were genotyped. In each experimental group of animals, only alleles without deletions in exon 10 and only allele A in exon 12 were found. In exon 8, only genotypes CC/CC, TT/CC and TT/TT were found. These genotypes are associated with femur breaking strength, bone diameter, bone marrow diameter and compact bone thickness. No significant effects of SNPs in exon 8 on bone characteristics were found.

The Difference

Abstract. An association between intelligence at age 7 and a set of five single-nucleotide polymorphisms (SNPs) has been identified and replicated. We used this composite SNP set to investigate whether the associations differ between boys and girls for general cognitive ability at ages 2, 3, 4, 7, 9, and 10 years. In a longitudinal community sample of British twins aged 2-10 (n > 4,000 individuals), we found that the SNP set is more strongly associated with intelligence in males than in females at ages 7, 9, and 10 and the difference is significant at 10. If this finding replicates in other studies, these results will constitute the first evidence of the same autosomal genes acting differently on intelligence in the two sexes.
