The genomes and history of domestic animals
This paper reviews how mammalian genomes are utilized in modern genetics for the detection of genes and polymorphisms (mutations) within domesticated animal (mostly livestock) genomes that are related to traits of economic importance to humans. Examples are given of how genetic analysis allows to determine key genes associated with the quality and quantity of milk in cattle and key genes for meat production. Various questions are reviewed, such as how contemporary methods of genome sequencing allow to maximise the effective detection of coding and regulatory DNA polymorphisms within the genomes of major domesticated mammals (cattle, sheep and pigs) and the history of their formation from the standpoint of genetics
Pionic Degrees of Freedom in Atomic Nuclei and Quasielastic Knockout of Pions by High-Energy Electrons
The nonlinear model of pionic condensate in nuclei by G. Preparata can be
efficiently verified by investigation of the quasielastic knockout process of
pions out of nuclei by high energy electrons. First, a momentum distribution
(MD) of the collective pions has a bright maximum at q=0.3 Gev.Second the
excitation spectrum of a recoil nucleus is concentrated at low energies E
lesser than 1MeV. The results for the pion knockout from mesonic clouds of
individual nucleons are absolutely different. The latter results are presented
both for pion and rho-meson clouds localized on nucleons.Comment: 13 pages, 3 figure
