What is comparative genomic hybridization (CGH) ?
373524
well,\n*CGH:is a molecular-cytogenetic method for the analysis of copy number changes( gains/losses)in the DNA content of tumor cells,method is based on the hybridization of fluorescently labeled tumor and normal DNA to normal human metaphase preparations,using epiflourescence microscopy and quantitative image analysis,regional differences in the fluorescence ratio of tumor vs.control DNA can be detected and used for identifying abnormal regions in the tumor cell genome,CGH will detect only unbalanced chromosomes changes,structural chromosome aberrations such as balanced reciprocal translocations,inversions can not be detected.

complementary gene is a gene whose effect is not visible until another gene (which complements it) is not present.

the frequency of a given phenotype. ie, the incidence of blonde hair, the incidence of brown hair, and the incidence of red hair. genotype frquency would be similar - incidence of BB (for brown hair) Bb (for brown hair) and bb (for blonde). Obviously, hair color is more than just one gene, but i think you get the idea.

two copies of chromosomes ion the same cell

Each chromosome in your body has an "identical pair"- there are two chromosomes that code for the same functions- one from your mother and one from your father.\n\nBecause they come from two sources, they are coding for the same functions, but may code differently for them (ie blue eyes as opposed to brown eyes).\n\nDuring prophase one, each chromosome duplicates into two sister chromatids joined by a centromere, and then the double stranded chromosome finds it's partner which is coding for the same thing (just came from the opposite parent), and is also double stranded.  Now you have a 4 stranded tetrad.\n\nGenetic variability comes from crossing over.  This is where the two chromatids closest together in the tetrad exchange some genetic information.\n\nFor example, two of the chromatids code for blue eyes, brown hair and shortsightedness.\nThe other two chromatids code for brown eyes, red hair and normal vision.\n\nDuring crossing over one chromatid from each pair forming the tetrad literally have ends "crossing over" and bits of information are exchanged.\n\nAfter crossing over, you have 4 chromatids with unique codings.  Using the example above, we may now have:\n-blue eyes, brown hair, shortsightedness\n-blue eyes, red hair, normal vision\n-brown eyes, brown hair, shortsightedness\n-brown eyes, red hair, normal vision\n\nWe now have genetic variability in each gamete produced from this meiotic division.

are you asking about DNA extraction or plant (apple tree) cross-breeding?

Genome analysis is used for analysing researching and studying genomes, gene sequencing is about knowing the genetic code of the DNA consisting of adenine, cytosine, guanine and thymine , gene cloning is production of identical copies of the target gene and stem cell research is still under study for various applications as inducing immunogenicity, prevention of cancer etc... All these help in knowing more about the DNA which is the basis of life.

Inside of each cell of the human body is a nucleus.  Inside of it are genes and chromosomes.  Inside of those are complex strands of proteins and amino acids that together are calle deoxyribonucleic acid or DNA.  This DNA contains the "blueprint" for an entire human being.  When two people mate, their DNA gets combined to form a new human, unique but having many characteristics shared by the parents' DNA.  Have you ever heard the term "genetic lottery"?  This is because each time the DNA from two humans is combined to make a third new human, the combination of DNA is to an extent random.  Only to an extent.  I inherited my mother's bad vision and my father's bad teeth.  I inherited my father's nose.  But I am taller than either of my parents.  My hair is a completely different color than either of theirs.  Sometimes DNA, genes, and chromosomes are imperfectly formed.  Each gene controls certain characteristics about a human being.  Completely normal parents can wind up having a baby with Downs' Syndrome (Mongolism, a type of mental and physical retardation).  Completely normal parents can wind up having a dwarf baby.  But other problems are passed down directly from one generation to the next.  Hemophilia is one example, the people whose blood won't clot.  They can bleed to death from a cut.  If they fall they can bleed internally until they die.  Hemophilia is passed down from one generations to the next in the female line.  Queen Victoria, who was related to most of the people of the royal and imperial houses of pre-World War One Europe, was a carrier of the genetic defect of hemophilia.  The women who carry this are usually immune to it.  It is the boys they give birth to that can suffer and die from uninterrupted bleeding due to this genetic defect.  How to prevent one's son from being hemophiliac if one is a female carrier?  Adopt.

In genetics, hybridisation is the process of mixing different species or varieties of organisms. \n\nIn molecular biology hybridisation is the process of joining two complementary strands of DNA. \n\nIn chemistry, hybridisation is the mixing of atomic orbitals to form new orbitals suitable for bonding.

Cloning is a method of reproduction used to copy a cell or an individual (producing a clone) from their DNA . Except when there are errors or mutations during copying, a clone is genetically identical to the original: it has the same DNA. In nature, certain non-sexual species, like bacteria, employ cloning for reproduction.

No. Humans and chimps are entirely reproductively isolated. Mating will not produce any kind of hybrid.

The first steps have already been taken: human organs and stem cells have already been grown in the laboratory. New strides in genetics research such as identifying genes which cause disease are moving the scientific community ever closer to cloning a human. It would be interesting to see if a clone of a genetically mutated animal or human would exhibit the same symptoms as its duplicate. If not, what is the difference?

I think you mean hybridized, or crossed, this is the proper term when different animals are combined.  For instance a horse crossed with a donkey is a mule.\n\nCloning is when organisms share exactly the same genetic material.  Clones are a natural occurrence in the plant kingdom.

I don't think that was a documentary.  \n\nGorillas, chimpanzees and humans may share a common ancestor, but we are far enough apart genetically that interbreeding would no longer be possible.  Each species has a different number of chromosomes in their cells for one thing.\n\nIt would take a lot more manipulation than artificial insemination to get a genetic hybrid of gorilla and human.
