Animal Breeding and Genetics

The International Journal of Animal Breeding and Genetics aims to publish animal breeding-related aspects of the life sciences.

In agriculture, #polyculture is the practice of growing more than one crop species in the same space, at the same time.

[Animal Breeding and Genetics @BreedingAnd]

Subsistence agriculture occurs when farmers #grow food crops to meet the needs of themselves and their families on smallholdings.

#Mutation: A sudden change in the #genotype of an organism. The term is most often used in reference to point mutations.

[Animal Breeding and Genetics @BreedingAnd]

#Repeatability: The proportion of total #phenotypic variation that is attributable to variations caused by #genetic and permanent environmental effects

[Animal Breeding and Genetics @BreedingAnd]

#Genetic engineering: also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using #biotechnology

[Animal Breeding and Genetics @BreedingAnd]

#Molecular genetics is a sub-field of biology that addresses how differences in structures or expression of #DNA molecules manifests as variation in organisms.

[Animal Breeding and Genetics @BreedingAnd]

Recombination: The observed new combinations of #DNA segments, or loci, or traits, which are different from those combinations exhibited by the #parents.

[Animal Breeding and Genetics @BreedingAnd]

Sequence: The linear arrangement of #nucleotides that make up #unbranched polymer chains of #DNA or #RNA.

#Genome-wide association study (#GWAS): A study that evaluates association of genetic variation with outcomes or traits of interest by using very large number of markers across the genome.

#Genetic gain: The amount of increase in performance that is achieved through genetic selection after one #generation of selection.

#Mixed farming is a type of farming which involves both the growing of crops and the raising of #livestock.

[Animal Breeding and Genetics @BreedingAnd]

#Pastoral farming is aimed at producing livestock, rather than growing crops. Examples include dairy farming, raising beef #cattle, and #raising #sheep for wool.

#Breeding value: The mean genetic value of an individual as a parent. It can be estimated as the average superiority of an individual's progeny relative to all other progeny under conditions of #random mating.

[Animal Breeding and Genetics @BreedingAnd]

#Linebreeding is a form of inbreeding that involves selection of mates on the basis of their relationships to a certain superior #ancestor.

[Animal Breeding and Genetics @BreedingAnd]

#Mitochondria: Small bodies in the cytoplasm of most plant and animal cells responsible for energy production.

[Animal Breeding and Genetics @BreedingAnd]

#Crossbreeding is defined as the process or the act of producing offspring particularly through #mating two purebred individuals but come from different breeds and varieties.

[Animal Breeding and Genetics @BreedingAnd]

#Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a #genetic identity closer to that of the parent.

[Animal Breeding and Genetics @BreedingAnd]

livestock, farm #animals, with the exception of poultry. In Western countries the category encompasses primarily cattle, #sheep, #pigs, #goats.

[Animal Breeding and Genetics @BreedingAnd]

#Independent culling: When #animals are culled if they do not meet all of the minimum levels of performance for a set of #traits.

[Animal Breeding and Genetics @BreedingAnd]

#Hardy-Weinberg law: A population is in #genotypic equilibrium if p and q are the frequencies of alleles A and a, respectively, and p2, 2pq and q2 are the genotypic frequencies of AA, Aa, and aa under the condition of #random #mating.
