What are the differences between using traditional methods of artificial selection and using various transgenic methods of altering crops?
Good question, and it has tremendous impact. Artificial selection is choosing only certain plants that have desirable traits to reproduce. It relies on the traits and genes that the plant already has, and tries to reinforce them. The hope is that if you only reproduce the plants with desirable traits, after many generations, that trait will be greatly enriched in your plant. This is how crops were first domesticated, and how they were altered for thousands of years. Artificial selection is also how the many different breeds of dogs have developed. Transgenic methods involve actually adding new genes, or genes from different plants/animals/bacteria into a crop. It requires much more than just selective breeding. It requires the genetic engineering of new plants, which is done in a lab, and involves the manipulation of the plant's DNA. This process is how people have developed versions of corn that are resistant to plant killers (so now farmers can spray Roundup plant killer on a field of corn, and kill everything except for the corn). Although the process is not dangerous on its own, there are some concern that the newly added genes can transfer to other plants as well, though after over ten years in public use and over a billion acres grown, there is still no proof of it.
What is artificial selection and how does it work in the process of breeding specific traits in plants or animals?
Artificial selection is a process where humans selectively breed plants or animals to develop specific desired traits. This is done by choosing individuals with the desired traits and allowing them to reproduce, passing on those traits to their offspring. Over time, this selective breeding can lead to the development of new varieties or breeds with the desired traits.
Do all plants produce seed?
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
What are two alternative methods of providing nutrients?
Two alternative methods of providing nutrients are through hydroponic farming, where plants are grown in a nutrient-rich water solution instead of soil, and through foliar feeding, where nutrients are sprayed directly onto the leaves of plants for absorption.
What are the most effective methods for controlling white scale insects on plants?
The most effective methods for controlling white scale insects on plants include using insecticidal soap, neem oil, horticultural oil, or introducing natural predators like ladybugs. Regularly inspecting plants for infestations and removing heavily infested branches can also help manage the problem.
How do you extract raw materials?
Raw materials can be extracted through various methods depending on the material. Common methods include mining (for metals and minerals), harvesting (for plants), drilling (for oil and gas), and farming (for crops). Extraction methods often involve physically separating the desired material from its natural source.
What are some natural methods for getting rid of gophers?
Some natural methods for getting rid of gophers include planting gopher-repellent plants like castor beans, using predators like owls or snakes, and installing barriers like wire mesh underground.

How are new variations of plants are normally provided?
New variations of plants are usually provided through traditional breeding methods, such as cross-pollination and hybridization. Plant breeders carefully select parent plants with desired traits and then cross them to create offspring with new combinations of genes. Advances in biotechnology have also led to the development of genetically modified plants with specific traits.
What are some methods that man use to grow new plants?
cuttage,grafting and layering are the methods man use to grow new plants
How can I quickly dry plants?
To quickly dry plants, you can use methods like air drying, microwave drying, or using a food dehydrator. These methods help remove moisture from the plants efficiently.
What are some natural methods for getting rid of pocket gophers?
Some natural methods for getting rid of pocket gophers include using predators like owls or snakes, planting gopher-repellent plants like castor beans, and installing barriers like wire mesh underground to prevent them from burrowing.
What is the definition of general tillage?
Tillage is manipulation of the soil with tools, methods and implements for getting optimum environmental conditions for seed germination, seeding establishment and growth of plants (crops).
Do all plants need seeds to reproduce?
no some plants use other methods to reproduce
What is conventional plant breeding?
it is the identification and selection of desireble plants of desired charecters
What are the two common methods for planting?
cultinvating and watering the plants
