because mass selection is crossing plants with desirable traits ,
controlled breeding is mating organism to produce offspring with certain traits
DESIRABLE TRAITS = CERTAIN TRAITS
so mass selection is consider a form of controlled breeding
Uncontrolled breeding is an antonym for selective breeding. It refers to breeding without deliberate selection for specific traits, allowing natural or random processes to determine the outcome.
Knowing the mode of reproduction of crops is important in plant breeding because it influences the breeding methods that can be used to develop new varieties. Crops that reproduce sexually require different breeding strategies compared to those that reproduce asexually. Understanding the mode of reproduction helps breeders choose appropriate techniques to achieve desired outcomes in crop improvement programs.
natural selecion
In natural selection, genetic traits are passed down based on survival advantages, with organisms inheriting traits that increase their chances of survival and reproduction. In selective breeding, humans intentionally choose specific traits to be passed down, regardless of their survival advantage, with the goal of producing desired characteristics in offspring for human benefit. The main difference is that natural selection is driven by environmental factors selecting for advantageous traits, while selective breeding is driven by human intervention selecting for specific traits.
Biotechnology plays a crucial role in plant breeding by enabling the development of genetically modified (GM) crops with desirable traits such as resistance to pests, diseases, and environmental stresses. Techniques like genetic engineering and gene editing allow for targeted modification of plant genomes to enhance productivity, nutritional value, and sustainability in agriculture. Biotechnology also accelerates the breeding process by providing tools for precise trait introgression and selection in plants.
plant or animal breeding
it is the identification and selection of desireble plants of desired charecters
Mass selection in animal breeding is when certain animals are chosen for certain desirable traits to pass on. Once those animals are obtained, they are bred to control what traits the offspring have and to create varying lines.
Recurent selection is a breeding method where the best performing individuals from one generation are selected as parents for the next generation in order to improve multiple traits over time. This approach is commonly used in plant breeding programs to accelerate the improvement of complex traits such as yield, disease resistance, and stress tolerance by promoting genetic diversity and combining favorable alleles through multiple rounds of selection and recombination. By incorporating recurent selection, breeders can drive genetic gain more efficiently and effectively target desired traits for improvement in plant populations.
Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.
False, dog breeding would be an example of Artificial Selection.
False, dog breeding would be an example of Artificial Selection.
Plant breeding techniques such as hybridization, selection, and genetic engineering are used to improve the phenotype of plants. These methods help enhance desirable traits such as yield, disease resistance, and quality, leading to the development of improved plant varieties.
The different methods of plant breeding for disease resistance includes seed selection, pedigree selection,recurrent selection,use of natural or artificial induced mutants etc.

he Power Plant Maintenance Positions Selection System (MASS) is a battery of skill and ability tests designed and validated to aid in the selection of candidates for power plant maintenance positions. This test battery measures the mental abilities found to be important for successful job performance. Reference: http://www.dom.com/jobs/tests.jsp
