What is the best explanation of PGD?
PGD is the abbreviated form for Preimplantation Genetic Diagnosis. This refers to procedures that are performed on embryos prior to implantation, sometimes even oocytes (female gametocytes or germ cells used in reproductions) prior to fertilizations. PGD is considered another way to prenatal diagnosis. Its main advantage is that it avoids selective pregnancy termination as the method makes it highly likely that the baby will be free of the disease under consideration. PGD thus is an adjunct to assisted reproductive technology, and requires in vitro fertilization (IVF) to obtain oocytes or embryos for evaluation. Hope this helps with your work.
What would most likely decrease the genetic variation in the human population?
A widespread disaster would reduce the variety within the human genetic pool by eliminating all but certain segments of the population. A global plague could potentially have the greatest effect, as plagues (see: black plague, Spanish influenza) often will often decimate all of a local population save for those with genetic immunity--thus standardizing that mutation in future populations. Global catastrophe could also inhibit travel, and would limit human reproduction to their immediate region, limiting the genetic range of potential offspring.
What is one factor that affects natural selection and artificial selection?
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
Genes from one organism are transferred into the DNA of another organism?
The process of transferring genes from one organism into the DNA of another organism is known as genetic engineering or genetic modification. This is typically done using techniques such as gene cloning, where a specific gene of interest is isolated and inserted into the DNA of the target organism. The goal of this process is to introduce new traits or characteristics into the target organism, such as increased resistance to pests or diseases. This technology has applications in agriculture, medicine, and biotechnology.
Under what circumstances would crossing over during meiosis not contribute to genetic variation among daughter cells?
Crossing over not contributing to genetic variation among daughter cells can occur if there is no exchange of genetic material between the homologous chromosomes during meiosis. This could happen if crossing over fails to occur due to genetic or environmental factors, leading to the daughter cells having identical genetic content.
What is gene cloning and gene modification?
Gene cloning is when you take the entire genetic profile to create a copy of the donor of the genes. Gene modification is when you change a persons genes, in a way to change the outcome of how the baby will look, act, her/his personality and a lot more. In this case, gene cloning would come under the category of gene manipulation.
How could you get a tall breed of dogs through selective breeding?
look at the book called the ultimate encyclopedia of dogs dog breeds and dog care it should say right under it
What are the views of Christians on genetic engineering?
Most Christians view genetic engineering as playing god. What they lack to understand is that their god created the Cosmos, sparked life, and designed that life. We humans are not designing life itself, but instead altering under the laws of life and nature.
What is variation under domestication and variation under nature?
Variation under domestication refers to the diversity in traits of domesticated animals or plants resulting from selective breeding by humans. Variation under nature refers to the diversity in traits of wild organisms shaped by natural selection and evolutionary processes in their natural habitats.
Why did Spidey lose his powers in Spider-Man 2?
Because he was under so much stress that the genetic engineering in his blood began to brake down.
Where do white tigers reproduce?
White tigers typically reproduce in captivity in zoos or breeding centers. Breeding of white tigers is closely monitored to prevent inbreeding and maintain genetic diversity within the population. There are efforts to conserve this rare and endangered species through controlled breeding programs.
Why isolation of a pure culture on selective medium may not be successful?
Isolation of a pure culture on a selective medium may not be successful due to factors such as contamination from other organisms, genetic variability within the target organism, or difficulties in selecting appropriate conditions for growth. Additionally, some organisms may not grow well under the specified selective conditions, leading to a lack of colony formation.
What is Silenced transmission of pressurized good breeding?
breeding under pressure
What is the difference between Genetic Engineering and Natural Reproduction on plants?
Genetic engineering is when scientists manipulate individual genes within organisms. EXAMPLE: Artificially introducing a gene from a jelly fish into a rabbit. the result is a rabbit that glows in the dark under an ultraviolet light source. This is one example. Natural reproduction is when that organism chooses to mate with another organism. You are not forced, its just natural.
Under genetic engineering what are polypeptides?
polypeptides are proteins. poteins are composed of amino acids that are liked via peptid bonds, hence the name: poly(a lot of)peptide(peptide bonds).
Which are good courses in engineering?
Some major fields of study under engineering are as follows. * Electrical engineering * Electronics engineering * Chemical engineering * Mechanical engineering * Engineering management * Architectural engineering * Civil engineering
