2 days ago · Definition. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA. For example, genetic engineering may involve adding a gene from one ...
5 days ago · In Ethiopia, four different methods have been implemented to define goat-keeper breeding objectives (Haile et al., Citation 2011). These include semi-structured questionnaires, choice card experiments, focus group discussions and phenotypic ranking of live animals.
2 days ago · Definition. Polymorphism, as related to genomics, refers to the presence of two or more variant forms of a specific DNA sequence that can occur among different individuals or populations. The most common type of polymorphism involves variation at a single nucleotide (also called a single-nucleotide polymorphism, or SNP).

5 days ago · Definition. Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker. By contrast, an individual who is homozygous for a marker has identical versions of ...
3 days ago · This is called a true breeding line. “A true breeding line is the one when self pollinated continuously, shows stable inheritance traits and expression for several generations forward”. True breeding line was first observed by Mendel and it is useful for studying the inheritance patterns and genetics of the plants by selecting various ...
4 days ago · Out- Crossing. Cross- Breeding. This is a practice of mating of animals within the same breed, but having no common ancestors on either side of their pedigree for up to 4- 6 generations. In this method, superior males of a breed are mated with superior females of another breed. The offspring of such a mating is known as an outcross.
