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.

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 gene knockout testing?
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.
What is characteristic arising from genes located on chromosomes that are not gender-determining.?
autosomal trait
How genes control cell function?
They do not.
What are genes and what role do they play?
Genes control the expression of (genetic) traits and are responsible for determining the inherited characters, they are therefore called units of inheritance.

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

A punnett square can be useful in determining genetic linkage?
Sort of. A Punnett Square is useful in determining the genetic linkage of a parent's offspring that have been conceived by sexual reproduction, where half of the genes come from the sire and the other half are from the dam. However, which half that the offspring gets from who is unknown unless we lay out the possibilities of such a resulting cross.
What name is given to genes that regulate the genes involved in determining patterns of anatomical development?
Homeotic gene
What part do nucleic acids and DNA play in determining inheritance?
in the GENES
What is the function of most genes?
Genes decide what all of our physical characteristics are

What role do chromosomes and genes play in determining a child's heredity?
Genes are the basic unit of genetic inheritance. Chromosomes are the structures inside cells that contain the entire genome. Naturally, genes and the chromosomes that contain them, and how genes arrange themselves on the daughter chromosomes during meiosis are critical to the process of determining the heredity of the offspring.
What is a characteristics arising from genes located on gender-determining chromosomes?
sex-linked trait
