Genetic trait referes to any genetically determined characterstics, it is specific characterstics of an individual, for eg, the blood group of an individual or color of hair or eye of an individual, genes that are passed on to the individual from his parents determine many of your traits, such as your hair color or skin color, traits are also determined by the interaction with the enviornment with genes.

A specific sequence of DNA at a known location on a chromosome is known as genetic marker. There are many genetic marker on each chromosomes. Genetic markers can be used to identify individuals or species in a population, they can be used tio identify genes involved in inherited disease. In human genome the most common type of genetic markers are Single nucleotide polymorphism (SNP) they are the most common type of genetic variation among people, each SNP represents a difference in a single nucleotide, for eg, SNP may replace nucleotide cytosine with nucleotide thiamine in a certtain stretch of DNA

Let’s model the inheritance of a genetic trait, for example eye color. Every individual has a pair of chromosomes for eye color, and an offspring gets one chromosome from each parent. Say a represents a brown-eye gene, and b represents a blue-eye gene, and that brown is dominant (meaning the eye will be brown if the individual carries at least one a gene, and only bb pair will result in blue eyes). The order in the pair does not matter....

It has been suggested that genetic correlation between the expressions of a trait in the two sexes is responsible for some apparently non-adaptive traits, such as nipples in men and the muted presence in many female birds of the bright colors used by males in their displays. Suggest ways of testing this hypothesis. What other traits might have evolved because they are genetically correlated with adaptive traits, rather than being adaptive themselves?
