Defenition Of Heredity and Genetics
Heredity is the passing on of characteristics from one generation to the next. It is the reason why offspring look like their parents. It also explains why cats always give birth to kittens and never puppies. The process of heredity occurs among all living things including animals, plants, bacteria, protists and fungi. The study of heredity is called genetics and scientists that study heredity are called geneticists.
Through heredity, living things inherit traits from their parents. Traits are physical characteristics. You resemble your parents because you inherited your hair and skin color, nose shape, height, and other traits from them.

1) Did you know that all our traits are set by some molecule of size 0.3 nanometer?
2) Have you heard about genetically custom made products and medicines?
3) Do you think that someday we will have the power to change our genes?

We are, our genes...
Did you know that your genes determine whether or not you possess certain physical traits? Well, they do. It's your genes that make you blue eyed or brown eyed, or have brown or blond hair. These traits are highly complex, and involve the interaction of many genes. However, several traits are determined by only one gene, and if you have the gene then you have the trait.
You have two genes for every trait. You get one from your mother and one from your father. Certain genes are dominant, and you only need one of the pair to give you its trait. If you don't have a dominant gene, then you are recessive for that trait.

1) Can a child get blue eyes, without any of his parents having blue eyes?
2) Does life experiments have impact on our genes?
3) Would you like to know what is mutation of genes?

A Gene Map of the Human Genome
The Human Genome Project is expected to produce a sequence of DNA representing the functional blueprint and evolutionary history of the human species. However, only about 3% of this sequence is thought to specify the portions of our 50,000 to 100,000 genes that encode proteins. Thus an important part of basic and applied genomic is to identify and localize these genes in a process known as transcript mapping. When genes are expressed, their sequences are first converted into messenger RNA transcripts, which can be isolated in the form of complementary DNAs (cDNAs). Approximately half of all human genes had been sampled as of 15 June, 1996.
A small portion of each cDNA sequence is all that is needed to develop unique gene markers, known as sequence tagged sites or STSs, which can be detected in chromosomal DNA by assays based on the polymerase chain reaction (PCR).To construct a transcript map, cDNA sequences from a master catalog of human genes were distributed to mapping laboratories in North America, Europe, and Japan. These cDNAs were converted to STSs and their physical locations on chromosomes determined on one of two radiation hybrid (RH) panels or a yeast artificial chromosome (YAC) library containing human genomic DNA. This mapping data was integrated relative to the human genetic map and then cross-referenced to cytogenetic band maps of the chromosomes.

1) Do you think that in 20 years, almost all therapy will be based on the genome studies?
2) In 2002 the National Institutes of Health started a $138 million project called the HapMap to catalog the common variants in European, East Asian and African genomes.Do you think it's worth it?
3) What benefits can you see from this project?
