Glossary
Chromosomes: which is made up of the DNA or the blue print of life, carry the entire genetic code. It contains many genes. The chromosomes are located in the cell nucleus and consists of genes. In humans there are 23 pairs of chromosomes(i.e 46 chromosomes), each pair contains one chromosome from each parent, The chromosome has two arms, a short p arm and long q arm. The word 'chromosome, comes from the Greek word 'chroma' means 'color' and 'soma' means 'body'Sex Chromosomes: There are 46 chromosomes in humans, of which two are the X and the Y(XX - in a female and XY in a male)
Chromosomal Disorders : A disorder caused by an abnormality in the number or structure of the chromosomes
Puberty : Onset of sexual maturity in a male or female child
Mosaic: An individual with two cell types or more, comprising of different chromosome number or structure
Genetic Counselling: A communicative procedure that undertakes to deal with the problems that rise in a family with the occurrence or the risk of occurrence of a genetic abnormality
Pedigree: A pedigree involves recording a family's history and making use of a standard set of symbols to represent the status of each member of the family

Chromosomes: Chromosomes are structures made up of DNA and proteins found in the cells of all organisms.The number of chromosomes is species- specific.In humans it is 46.
DNA: The DNA is the basic unit of heredity and is known as the blue print of life.It carries the genetic codes which stores the necessary information for all organisms.
Genotype: Genotype indicates the genetic constitution of an organism
Phenotype: Phenotype refers to the physical appearance of an organism which is controlled by the genotype and the enviornment
Haploid Cell: A cell having only one set of chromosomes, ie. 23 numbers in humans
Diploid Cell: Having two sets of chromosomes,46 numbers in humans

Mutation: An inheritable change in the gene or the chromosome
Wild Type: An organism having a normal phenotype
Mutant: An organism harboring a mutation
Trisomy: A condition,which arises due to the presence of an extra chromosome.An example is Down syndrome, where the individual has an extra chromosome 21
Mitosis: A division by which the cells reproduce, wherein the resultant cells are the replica of the parent cell.
Meiosis: A special kind of cell division,called reduction division, that takes place in the testes and the ovaries, which produces eggs and sperms that are haploid
Consanguinous marriage: A marriage between two closely related individuals
Euploidy: When an organism has the regular chromosome number,example 46 numbers in humans, it is euploid.
Aneuploidy: When an organism has an abnormal number of chromosomes as in Down Syndrome,it is known as aneuploidy.

The enlarged breast in men is called gynocomasta. The doctors are not very shure why it happens, but imbalance in the testosterone level can be one reason others can be drug abuse etc. The only solution is Surgery. General surgeon can perform the surgery under local anesthesia[ means injecting the chest are with a numming agent] and you will be released out in the same day. Liposuction is another good solution where the surgeon will pull out the fats form the breast using a surgical needle with a pipe attached to a pump and you will be released in a few hours after dressing. You have to be lying flat on the bed for one week wearing a belt and then after opening the stitches you will be asked to not pull weight for a month or so after that you will leave a normal life. But before surgery get in touch with doctors of the ENDOCRINOLOGY department will ask you to preform some blood tests and some scans to identify the cause of your problem- I AM A FORMER GYNACOMASTIYA PATIENT
