چکیده
Faktor genetik pada pewarisan bobot hidup ternak adalah nilai pemuliaan, deviasi dominansi dan heritabilitas. Penelitian ini bertujuan mengidentifikasi komponen genotipe pemuliaan serta heritabilitasnya sapi Peranakan Ongole Lokal. Total 74 induk generasi awal (G0), 104 1 (G1) dari pejantan dianalisis kontribusi genetik. Lokus gen (gen O) Lokal L) hasil pengukuran OO, LL LO melalui dominan gen. Program statistik Excel XP digunakan menganalisis data. Hasil penelitian menunjukkan bahwa rata-rata populasi tetua (µ) (G0) 340,01 ± 6,12 kg. Sedangkan rara-rata (µ1) keturunan 359,60 5,67 kg, dengan respon seleksi (∆µ) sebesar 19,59 Komponen homozigot OO sangat didominasi oleh aksi aditif lebih tinggi untuk daripada dominan. Genotipe heterozigot pula yang rendah aditif. Heritabilitas (h2) sebagai 0,66 kategori tinggi, sedangkan () 0,33 dikategorikan heritabilitas sedang.Kata Kunci: Nilai dominan, hidup, Campuran Lokal-Ongole

Role of staphylococcal phage and SaPI integrase in intra- and interspecies SaPI transfer.
SaPIbov2 is a member of the SaPI family of staphylococcal pathogenicity islands and is very closely related to SaPIbov1. Typically, certain temperate phages can induce excision and replication of one or more of these islands and can package them into special small phage-like particles commensurate with their genome sizes (referred to as the excision-replication-packaging [ERP] cycle). We have s...
متن کاملSaPI operon I is required for SaPI packaging and is controlled by LexA.
Transfer of Staphylococcus aureus pathogenicity islands (SaPIs) is directly controlled by the cellular repressor LexA. We have found that transcription of the SaPIbov1 operon I is repressed by LexA and is therefore SOS-induced. Two copies of the LexA binding site consensus (Cheo box) are present in the 5' region of this operon, at the same location in all of 15 different SaPIs analysed. Both of...
متن کاملSWI-Speech: An Interface Between SWI-Prolog and Microsoft SAPI
This paper describes the implementation and use of SWI-Speech, an interface between SWI-Prolog and Microsoft SAPI (Speech Application Programming Interface). SWI-Speech is a component of PRONTO (Prolog Natural Language Toolkit), a package created by the Artificial Intelligence Center at the University of Georgia. This paper is divided into a discussion of how to use the current version of SWI-S...
