Explanation: Selective breeding is the process of crossing of two selected varieties having different traits to produce a hybrid having good traits of both e.g. some breeds of sheep possess only soft under-hair.

Genetic engineering made it possible to create crop varieties regarded as “more beneficial”. Unlike selective breeding modern genetic engineering is more gene-specific. One of the downsides of selective breeding is the possibility of generating traits that are less desirable.

How has genetic engineering helped farming?
The most commonly introduced genetically engineered (GE) traits allow plants either to produce their own insecticide reducing crop losses to insect damage or to resist herbicides so that herbicides can be used to kill many types of weeds without harming crops.
What Is The Difference Between Genetic Engineering And Selective Breeding?
Selective breeding makes use of existing naturally present gene variants in a species? and the natural process of breeding. Genetic engineering involves a direct change to an organism’s genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.Jul 21 2021
What type of science is genetic engineering?
Genetic engineering also called recombinant DNA technology involves the group of techniques used to cut up and join together genetic material especially DNA from different biological species and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.
What is the difference between breeding and selective breeding?
New varieties Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally but selective breeding only occurs when humans intervene.
Where is selective breeding used?
Since the time man first domesticated animals selective breeding has been used to develop better or more useful strains (or breeds) of the animals from the genetic diversity that naturally exists in the population of a single species.
What is an important difference between mRNA and DNA?
DNA is made up of deoxyribose sugar while mRNA is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded. See also what makes russia distinctive

Are inbreeding and hybridization opposite processes?
Inbreeding and hybridization are opposite processes. b.A hybrid plant has all the characteristics of both its parents. … Hybridization is used to produce new varieties of plants and animals.
What is the difference between genetic engineering and selective breeding quizlet?
What are differences between genetic modification and selective breeding? Genetic modification is faster as you don’t have to wait for the organism to reproduce as you have to in selective breeding. … They are both instances of humans manipulating another organism to benefit themselves not the organism.

What means genetic engineering?
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. … Genetic engineering involves the direct manipulation of one or more genes. Most often a gene from another species is added to an organism’s genome to give it a desired phenotype.
What is selective breeding done by?
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
What are the 6 steps of genetic engineering?
Stages of genetic engineering to include:
- identify section of DNA that contains required gene from source chromosome
- extract required gene
- insert required gene into vector/bacterial plasmid
- insert plasmid into host cell
- grow transformed cells to produce a GM organism.
