A knockout organism is an organism that's missing a functioning gene. They're used to test the function of genes and genetic diseases, because a researcher can observe specific changes in a gene knockout organism's gene expression and traits.

How are gene knockout organisms used in determining the function of genes?
Gene knockout organisms are animals, usually mice and rats, who have been genetically engineered so that one of their genes is removed or knocked out. The ways in which their behaviour or appearance deviates from normal shows what the function of that gene is. For example, if the animals cannot stop eating and eat themselves to death, then it is clear that the genes are essential to the animal's ability to feel full and so stop eating. Knockout mice can also be used to test the effect of drugs and medication: if the drug has an effect on normal mice but not on the knockout mice then clearly the drug works through the mechanism which is controlled by the missing gene.

What is meant by 'randomly assorting epistatic genes'?
A gene who's presence supresses the effect of a gene at another locus.
How are the knockout mice useful in determining the function of genes?
Knock out mice are produced by impairing or deleting a particular gene expression. Thus the gene function (which was deleted) can be tracked by studying this knock out and the control mice. Lets say a gene is suspected to trigger immune response against a pathogen, one can study this by infecting the wild type(normal) and knock out(specific gene deleted) mice and study the role of the gene.
Where can one find information about Sibling DNA Testing?
Someone can find information about Sibling DNA testing from a number of websites such as Gene Track Canada. The website contains extensive information about sibling DNA testing and also provides locations where individuals can go to get sibling DNA testing done.
What are knockout animals?
Animals that have knockout genes. Knock out gene:A gene knockout (abbreviation: KO) is a genetic technique in which an organism is engineered to carry genes that have been made inoperative (have been "knocked out" of the organism). This is done for research purposes. Also known as knockout organisms or simply knockouts, they are used in learning about a gene that has been sequenced, but which has an unknown or incompletely known function. Researchers draw inferences from the difference between the knockout organism and normal individuals. The term also refers to the process of creating such an organism, as in "knocking out" a gene. The technique is essentially the opposite of a Gene Knock-in. Knockout is often abbreviated as KO. Knocking out two genes simultaneously in an organism is known as a double knockout (DKO). Similarly the terms triple knockout (TKO) and quadruple knockouts (QKO) are used to descripe 3 or 4 knocked out genes, respectively.Source: http://en.wikipedia.org/wiki/Gene_knockout
Definition of conditional knockout?
A conditional knockout is the event in which a gene can be specifically inactive within tissue. This can be accomplished in most tissue types including the brain, muscles, skin, and intestines.

What are general Phenotypic characteristic features of a knockout mice other than the specific gene knockout or how can we conclude a mice is knockout mice without any molecular biology techniques?
In simple words, you can not conclude without molecular data. You may sometimes see a visible phenotype such as change in color of eyes, skin or growth or any such things for some genotype. but this doesn't validate that the gene knock out actually happened in both allele.

How can the defective gene causing lipidoses be identified?
Genetic testing can be used, in some cases, to identify the defective gene causing lipidoses.
What is the definition of candidate gene testing?
A candidate gene is a probable cause for a disease. The gene can become a candidate based it's location is a chromosome region that is suspected of being the loci.
