Selective breeding uses natural biological means to alter genetics--example is using a pollen from one strain to fertilize another strain and so "cross" the gene pools.While on the on the hand genetic engineering artificially goes into the chromosomes to edit them--an unnatural process. Example--a cold water fish gene is put into a crop so that it won't freeze in the winter. This would not naturally occur.

How gentic traits inheritance differ in natural selection vs selective breeding?
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.
What does the term strain mean in relation with genetic crosses?
In genetic crosses, the term "strain" refers to a specific genetic line or variety of organisms that are pure-breeding for certain traits. Strains can differ in their genetic makeup and can be used in breeding experiments to study inheritance patterns and gene expression.
How does CRISPR differ from other methods of genetic engineering in terms of its precision and efficiency?
CRISPR is more precise and efficient than other methods of genetic engineering because it allows scientists to target specific genes with greater accuracy, making it easier to edit and modify DNA sequences. This precision helps reduce the risk of unintended genetic changes and increases the efficiency of the editing process.
How did Mendel's scientific work differ from the work of T.A. knight?
Mendel's work focused on pea plants and the inheritance of traits through controlled experiments, leading to the discovery of the principles of segregation and independent assortment. Knight's work involved cross-breeding different plant varieties to create new hybrids with desirable traits, but he did not uncover the underlying genetic principles as Mendel did. Mendel's work laid the foundation for modern genetics, while Knight's work contributed to the development of new plant varieties through selective breeding.
How does shotgun cloning differ from the clone-by-clone method in genetic engineering techniques?
Shotgun cloning involves randomly breaking up the DNA of an organism and then piecing it back together, while the clone-by-clone method involves isolating and sequencing individual DNA fragments before assembling them in a specific order. Shotgun cloning is faster but less precise, while the clone-by-clone method is slower but more accurate in genetic engineering techniques.
How does breeding differ from gentic engineering?
Breeding is more natural that Genetic engineering. Breeding is simply that you take sperm from the male animal of that species and inserted into the female either naturally or by artificial insemination. Genetic Engineering is when add genes from different things into that animal. This is usually done in a lab.
How is selective breeding related to genetic modification?
Selective breeding and genetic modification are both methods used to enhance desirable traits in organisms, but they differ fundamentally in their approach. Selective breeding involves choosing parent organisms with specific traits to produce offspring with those traits over multiple generations, relying on natural genetic variation. In contrast, genetic modification involves directly altering an organism's DNA using biotechnological techniques, allowing for more precise and immediate changes. While both aim to improve traits, genetic modification can introduce traits from unrelated species, whereas selective breeding works within the confines of existing genetic variation.

How does GMO differ from an individual of conventional breeding?
Conventional breeding is vertical breeding within the same species. Genetic modification is horizontal breeding, which removes a gene from one organism and inserts it into an unrelated organism. The transgenic individual carries the gene from the unrelated species, while the individual from conventional breeding does not.
How does selective breeding differ from evolution?
Selective breeding happens within closely related species. useful TechniquesGM Food produces a wide range of characteristics that aren't possible with selective breeding. It can alter an organism's DNA with much greater precision-genes can also be transfered or manipulated

Inbred lines that have same genetic constitution but differ only at one locus are called?
Inbred lines that have the same genetic constitution but differ only at one locus are called "near-isogenic lines" (NILs). These lines are used in genetic studies to isolate the effects of specific genes on traits, allowing researchers to assess the impact of single genetic variations in a controlled genetic background. NILs are valuable in plant and animal breeding as they help in understanding gene function and developing improved varieties.
How do donkeys from Honduras differ from donkeys in Spain?
I would guess they differ because of breeding.
