susceptibility to disease. Chromosomes are the structures that are made up of thousands of genes. Chromosomal disorders are caused by an abnormality of chromosome number or structure. According to the Encyclopedia Britannica (2012) chromosomal disorders are defined as any syndrome characterized by malformations or malfunctions in any system of the body which are caused by an abnormal chromosome number or structure. The normal and abnormal number and structures of genes and chromosomes are the foundation

have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes from a cell. The 2 chromosomes in each pair are called homologous chromosomes or homologs. The sex chromosomes are X and Y. Human females have a homologous pair of X chromosomes (XX). Human males have one X and Y chromosome. The 22 pairs of chromosomes that do not determine sex are called autosomes. Each pair of homologous chromosomes includes one chromosome from each parent. The 46 chromosomes in a human somatic

remain virgin. BASIC GENETICS The karyotype of Drosophila comprises four pairs of chromosomes‚ of which three pairs are autosomes and one pair are sex chromosomes. Female Drosophila are XX‚ and males XY. A gene is a heritable factor that controls the expression of some trait‚ which may be morphological‚ behavioural‚ molecular‚ etc. Each such gene occupies a specific physical locus (pl. loci) on a particular chromosome. Variant forms of these loci are termed alleles. Gene‚ locus‚ and allele are often

contribute to its determination. There are numerous determinants that control sex determination‚ but the most important are sex chromosomes and environmental factors. Sex chromosomes is the process where either of a pair of chromosomes determine whether an individual is male or female. In humans‚ the sex chromosomes are represented by X and Y and found on chromosomes

Function- To grow repair and maintain the cells in the body along with the reproduction of those cells. Results- Two identical daughter cells form from the parent cell. Phases of Mitosis Prophase- Nucleus disappears‚ chromatin forms into chromosomes. Centrioles start to move to outer poles. Spindle fibers start to form Metaphase- Centrioles have moved to the outer poles‚ spindle fibers connect to the centromeres. Chromatids are guided to the middle of of the cell by the spindle fibers.

other ways. Color blindness can also happen if physical or chemical damage is done to the eye‚ the optic nerve‚ or parts of the brain. The gene that produces photopigment is on the X chromosome. The X chromosome is sex-linked which is why color blindness usually is more dominant in males. Males have only one X chromosome. If this gene is

DNA is a self-replicating material that is in almost all living organisms as the main part of chromosomes. Ribonucleic acid or RNA is a nucleic acid that is in all living cells. Its main role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. A mutation is a part of your genetic code that is changed. So
