Fish gonadogenesis. Part I: genetic and environmental mechanisms of sex determination

DJ Penman, F Piferrer - Reviews in Fisheries Science, 2008 - Taylor & Francis
Many species of fish produced in aquaculture or for the ornamental fish trade exhibit sexual
dimorphism in growth, age at maturity, secondary sexual characters, or other traits of interest. …

[HTML][HTML] The genomic substrate for adaptive radiation in African cichlid fish

…, M Nikaido, H Nishihara, C Ozouf-Costaz, DJ Penman… - Nature, 2014 - nature.com
Cichlid fishes are famous for large, diverse and replicated adaptive radiations in the Great
Lakes of East Africa. To understand the molecular mechanisms underlying cichlid phenotypic …

[HTML][HTML] Development and validation of a high density SNP genotyping array for Atlantic salmon (Salmo salar)

…, SC Bishop, AL Archibald, JE Bron, DJ Penman… - BMC genomics, 2014 - Springer
Background Dense single nucleotide polymorphism (SNP) genotyping arrays provide
extensive information on polymorphic variation across the genome of species of interest. Such …

Genetics of sex determination in tilapiine species

…, A D'Hont, JF Baroiller, H D'Cotta, DJ Penman… - Sexual …, 2008 - karger.com
… Markers from LG3 always localize to the largest tilapia chromosome, and markers from LG1
to a smaller chromosome [DJ Penman, unpublished results]. The two loci also differ in their …

Identification of a sex‐determining region in Nile tilapia (Oreochromis niloticus) using bulked segregant analysis

BY Lee, DJ Penman, TD Kocher - Animal genetics, 2003 - Wiley Online Library
Sex determination in the Nile tilapia (Oreochromis niloticus) is thought to be an XX‐XY (male
heterogametic) system controlled by a major gene. We searched for DNA markers linked to …

Masculinization of genetic female Nile tilapia (Oreochromis niloticus) by dietary administration of an aromatase inhibitor during sexual differentiation

…, BJ McAndrew, DJ Penman - Journal of …, 2000 - Wiley Online Library
A series of experiments was carried out in which genetically female Nile tilapia (Oreochromis
niloticus) fry were treated with Fadrozole, a nonsteroidal aromatase inhibitor (AI), in the diet …

[HTML][HTML] A high quality assembly of the Nile Tilapia (Oreochromis niloticus) genome reveals the structure of two sex determination regions

MA Conte, WJ Gammerdinger, KL Bartie, DJ Penman… - BMC genomics, 2017 - Springer
Background Tilapias are the second most farmed fishes in the world and a sustainable
source of food. Like many other fish, tilapias are sexually dimorphic and sex is a commercially …

Cloning of brain aromatase gene and expression of brain and ovarian aromatase genes during sexual differentiation in genetic male and female Nile tilapia …

…, BJ McAndrew, DJ Penman - Molecular Reproduction …, 2001 - Wiley Online Library
A brain aromatase gene was identified from the Nile tilapia Oreochromis niloticus. The cDNA
sequence of this gene differed from that of the ovarian aromatase gene previously reported …

[HTML][HTML] Mapping and Validation of the Major Sex-Determining Region in Nile Tilapia (Oreochromis niloticus L.) Using RAD Sequencing

…, JB Taggart, K Gharbi, BJ McAndrew, DJ Penman - PloS one, 2013 - journals.plos.org
Sex in Oreochromis niloticus (Nile tilapia) is principally determined by an XX/XY locus but
other genetic and environmental factors also influence sex ratio. Restriction Associated DNA (…

Sex determination in the genus Oreochromis 1. Sex reversal, gynogenesis and triploidy in O. niloticus (L.)

GC Mair, AG Scott, DJ Penman, JA Beardmore… - Theoretical and Applied …, 1991 - Springer
Established techniques of genetic manipulation were used to elucidate sex-determining
mechanisms in the commercially important tilapia, Oreochromis niloticus. Analysis of sex ratios …
