Weight is a quantitative trait and mice with defective leptin tend to have problems controlling weight since this gene is associated with it.
<h3>What is a quantitative trait?</h3>
A quantitative trait is a phenotypic feature controlled by many genes and the interaction with the environmental factors.
Weight, height, behavioral features are all examples of quantitative traits because these types of phenotypic features show continuous variation.
Quantitative traits are modulated by gene interactions and therefore exhibit both epistatic and pleiotropic effects.
The leptin gene is a gene in mammal involved in neuronal control to metabolic signals and thereby it is associated with weight.
In conclusion, weight is a quantitative trait and mice with a defective form of the leptin gene tend to have problems controlling weight because it is associated with this trait.

The designated "universal genetic code" is the complex information system contained within DNA and is unique to every species and overall similar within all organisms.
There is no remaining DNA from the earliest organisms, but there is every evidence that all organisms that exist or have ever existed utilize DNA as the basis of the universal genetic code that configures life and regulates evolution.
Evolution does not occur without replication and replication does not occur without DNA. The structure of all organisms is protein based, which are virtually all specified by DNA, which itself is made up of proteins. A serious chicken and egg conundrum.
Present hypotheses about the origin of life, OoL, are restricted to purely natural conditions and causes for OoL because of the ideological belief called philosophical naturalism, but tis cannot explain the origin of DNA.
DNA is multi-level organically coded, intelligently designed and irreducibly complex, homochiral structured, most complex information in the universe, bar none. It has no natural process explanation. It is the basis for all evolution and the common design of all organisms.
Current naturalistic propositions about OoL will never find the source of OoL or explain the creation of DNA.

<span>It is used to develop the
tree of life and understand relationship between organisms. This study enables scientists comprehend the morphology and behaviour of organism. Its study is also
significant in medicine in understanding the evolution of diseases and hence important
in drug development. </span>
