Detailed explanation-1: -Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you-or inherited-from your parents. Each cell in the human body contains about 25, 000 to 35, 000 genes.
Detailed explanation-2: -The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits.
Detailed explanation-3: -The inheritance of each trait is determined by ‘factors’ (now known as genes) that are passed onto descendants. Individuals inherit one ‘factor’ from each parent for each trait. A trait may not show up in an individual but can still be passed onto the next generation.
Detailed explanation-4: -DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleus and mitochondria. Except for certain cells (for example, sperm and egg cells and red blood cells), the cell nucleus contains 23 pairs of chromosomes.
Detailed explanation-5: -The physical site or location of a specific gene on a chromosome.
