Conservation genetics of amphibians [PDF]
Heredity, 2005 Amphibians are good models for investigating the genetics of wild animal populations because they are: (1) widely distributed in most ecosystems; (2) easy to sample in breeding assemblages; (3) often philopatric to breeding sites, generating high levels of population genetic structure; (4) amenable to controlled crossings in the laboratory; and (5) of ...

Evaluation of Genetic Potential of Iranian Native Chicken Ecotypes; Insights for Conservation [PDF]
مجله بیوتکنولوژی کشاورزی, 2022 ObjectiveDifferent climates and wide geographical area of Iran have caused considerable genetic diversity in Iranian chicken ecotypes. Artificial selection for genetic gain in economic traits leads to a reduction of genetic diversity in livestock and ...

Genetic Selection and Conservation of Genetic Diversity* [PDF]
Reproduction in Domestic Animals, 2012 ContentsFor 100s of years, livestock producers have employed various types of selection to alter livestock populations. Current selection strategies are little different, except our technologies for selection have become more powerful. Genetic resources at the breed level have been in and out of favour over time.

Molecular Characterizations of Kenyan Brachiaria Grass Ecotypes with Microsatellite (SSR) Markers
Agronomy, 2017 Brachiaria grass is an emerging forage option for livestock production in Kenya. Kenya lies within the center of diversity for Brachiaria species, thus a high genetic variation in natural populations of Brachiaria is expected. Overgrazing and clearing of
