Different animals have different numbers of genes (and chromosomes). The exact number of genes that animals have has not been proven for many species, so estimates have been made.
It is estimated that humans and mice have approximately 20,000 genes, roundworms have approximately 13,000 genes and yeast has around 6,000 genes.
It should be noted that, similar to chromosome number, a larger number of genes does not necessarily mean the organism is more complex - for example rice has over 46,000 genes.

What do all animals pass on to their offspring in reproduction?
genes 23 from each parent
What animal has the most genes?
The animal with the most genes is theorized to be the marbled lungfish, which has around 132,000 genes. This is significantly more than the average number of genes in most animals, which typically range from 20,000 to 40,000.
Why do animals reproduce themselves before they die?
Animals reproduce to pass on their genes to the next generation, ensuring the survival of their species. By producing offspring before they die, animals increase the chances of their genes being passed on and perpetuating their genetic lineage. Reproduction is essential for the continuation of a species and the preservation of genetic diversity.
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
How have appendages of arthopods changed during evolution?
The HOX genes found in arthropods are a good example of how evolution may affect the overal structure of organisms. Arthropods are segmented organisms, and the development of segments and limbs in animals is regulated by HOX genes. As HOX genes change, the number of segments and limbs may change. Geneticists can demonstrate this by knocking out or otherwise altering the HOX genes in insects, causing abnormal development to occur, like extra segments, extra legs, legs for antennae, and so on. Today, there exists a wide variety of arthropods, each with a unique body plan and morphology. So too have their appandages diverged into many different forms.
How many methods exist for producing transgenic animals and what are they?
This will depend on the animal. These kinds of animals are ones that have foreign genes inserted into them.
What animals share the same genes as the platypus?
No animals share the same genes as the platypus. To suggest they do would be to suggest the platypus is a mixture of other animals which, or course, it is not.
Do animals and plants have DNA?
no animals and plant cells can not have the same genes.
Are genes found only in animals?
No, genes are found in all living organisms, including animals, plants, bacteria, and fungi. Genes are units of heredity that contain instructions for building and maintaining an organism.
Why do common patterns of genetic control for development exist in animals?
They exist because all these genes have descended from the genes of common ancestors.
How did rabbits have long ears?
The genes of animals it originates from.
Where does an animal get its genes?
Animals can get their traits from their parents or from their environment.
Why do animals compete against each other?
Animals compete because they need to ensure their genes are passed on to the next generation. The animals with the best genes/adaptions are more likely to survive and successfully mate therefore passing their genes on. The process of which the strongest (or just best suited to the environment) genes survive on to the next generation is called natural selection.
Does animal testing mutate the animals?
does animal testing mutate the animalsyes, it mutates the animals genes
How do animals adapt in their enviorment?
they adapt by mutations in their genes when they have newborns.
Where do animals get their colors?
They inherit their colors from the genes they inherit from their parents.
What animals will share the most genes?
The animals that will share the most genes are those that are the most closely related. Supporting theories that human evolved from primates, humans share a lot of genetic similarities with apes and monkeys.
