Explain the importance of understanding genetics and heritability. what might a geneticist study and how could that help living things on earth? use specific examples and include the basic structure of function of genes

Heritability is a measure of how one person differs from the other based on their genetic make up. Differences in genes or their make up leads to differences in their traits or characteristics such as height, eye color, and intelligence. Genetics and its applications have a wide variety of applications serving the human mankind. This includes the detection of many diseases like cancer at early stages,treatment of diseases, forensic applications with DNA fingerprinting, Cross breeding in both plants and animals to obtain high quality products with desired traits like, taste, fertility, size, disease resistance etc. Genetic enineering and Biotechnology has carved a niche of its own in th field of Science these days and is a promising feild which would address many problems faced by the world today.

Gene structure is the organisation of specialised sequence elements within a gene. Genes contain the information necessary for living cells to survive and reproduce. In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.

Genes are what is inherited from an organism's parents and what give the offspring certain characteristics of the parents, and alleles are different forms of a gene. For example, there are several different alleles for eye color genes, such as blue alleles (blue eyes) and brown alleles (brown eyes).

Explanation:

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
