What are the pros and cons of selective breeding?

Selective breeding is an extremely efficient way to good genetics in certain crops and livestock. However if you are concerned about the cons of it such as a genetic depression or discomfort to animals the alternatives can be much worse such as carrying out genetic modification.

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.

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.

Which best describes a difference between cloning plants and selectively breeding plants quizlet?

Which best describes a difference between cloning plants and selectively breeding plants? … Cloning results in a genetically identical plant and selective breeding does not.

What are researchers doing to the mutated gene when they use gene therapy?

Researchers are testing several approaches to gene therapy including: Replacing a mutated gene that causes disease with a healthy copy of the gene. Inactivating or “knocking out ” a mutated gene that is functioning improperly. Introducing a new gene into the body to help fight a disease.

What statements describe gene therapy?

Gene therapy is when DNA is introduced into a patient to treat a genetic disease. The new DNA usually contains a functioning gene to correct the effects of a disease-causing mutation. Gene therapy uses sections of DNA? (usually genes?) to treat or prevent disease.

Is selective breeding better than transgenesis?

In this example transgenesis is much more efficient than selective breeding because: selective breeding can only be used within the same or closely related species whereas the gene for Bt toxin is found in a very different organism. … with transgenesis only the specific gene for the specific trait is transferred.

How is biotechnology different from genetic modification?

What is the difference between Genetic Engineering and Biotechnology? Genetic engineering is the modification of genome of an organism to yield a desired outcome whereas biotechnology is the use of a biological system product derivative or organism in a technological aspect to benefit financially.

What is the main purpose of genetic engineering?

Genetic engineering allows scientists to select one specific gene to implant. This avoids introducing other genes with undesirable traits. Genetic engineering also helps speed up the process of creating new foods with desired traits.

What are some advantages and disadvantages of genetic engineering?

What Are the Advantages of Genetic Engineering?
  • It allows for a faster growth rate. …
  • It can create an extended life. …
  • Specific traits can be developed. …
  • New products can be created. …
  • Greater yields can be produced. …
  • Risks to the local water supply are reduced. …
  • It is a scientific practice that has been in place for millennia.

How does selective breeding affect the ecosystem?

Selective breeding can result in better quality products and higher yields in plants and animals that have been bred for specific characteristics. … Disadvantages include a reduction in genetic diversity and discomfort for animals that have very exaggerated characteristics.

How does selective breeding provide evidence for evolution?

Selective breeding of domesticated animals shows that artificial selection can cause evolution. Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function. Populations of a species can gradually diverge into separate species by evolution.

How are selective breeding and natural selection similar and different?

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. For this reason selective breeding is sometimes called artificial selection.

What is wrong with selective breeding?

Risks of selective breeding: reduced genetic variation can lead to attack by specific insects or disease which could be extremely destructive. rare disease genes can be unknowingly selected as part of a positive trait leading to problems with specific organisms eg a high percentage of Dalmatian dogs are deaf.

Why selective breeding is useful for farmers?

By selectively breeding animals (breeding those with desirable traits) farmers increased the size and productivity of their livestock. … Plants could also be selectively bred for certain qualities.

What is the difference between selective breeding and cross breeding?


How is selective breeding a form of biotechnology?

How is selective breeding a form of biotechnology? Biotechnology means to use technology invention or method on an organism which is what selective breeding is. It uses technology and methods to alter genes of organisms for human benefit.

How does selective breeding work?

How does selective breeding work? Farmers select parents with desirable characteristics and breed them together. From their offspring they again choose those with the best combination of traits and the process continues over many generations .

What are the 4 main differences between DNA and RNA?

DNA is a long polymer with deoxyriboses and a phosphate backbone. Having four different nitrogenous bases: adenine guanine cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine guanine cytosine and uracil.

How are RNA and DNA similar How do they differ?

Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine Adenine and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). … Secondly DNA is double-stranded while RNA is single stranded. Thirdly DNA is more structurally stable compared to RNA.

Which of the following are differences between DNA and RNA select all that apply?

The correct answer is – a b c d g and h. Different sugars present in the nucleotide Deoxyribose sugar in DNA and ribose sugar in RNA. There are different nitrogenous bases also present as RNA has uracil instead of thymine. DNA normally found in double-stranded while RNA exists in single-stranded.

What is selective breeding and what is the difference between its two methods hybridization and inbreeding?

Hybridization is one of the methods of selective breeding in which two dissimilar organisms undergo breeding. Also it produces a hybrid vigor in the offspring. … In contrast inbreeding is the second method of selective breeding in which two similar organisms undergo breeding.

What is selective breeding called?

Selective breeding is also known as artificial selection.

How are the selective breeding techniques hybridization and inbreeding opposites?

Why are they considered forms of selective breeding? Hybridization and inbreeding are opposites on the spectrum of genetic diversity. Hybridization creates offspring that are very different from either parent genetically and will be very heterozygous (the alleles from each parent are likely to be very different).

Which best describes genetic modification?

Biotechnology uses a procedure called genetic engineering. Which best describes genetic engineering? Which best describes genetic modification? It is used to alter crops to become insect-resistant.

Which best describes the process of 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.
