There are 46 chromosome in the human i.e. 22 pairs of autosome and 1 pair of sex chromosome. In male is XY and in female it is XX.. Introduction . The human genome consists of at least 20,000 genes on 23 pairs of chromosomes. Of these pairs, 22 are autosomes, and the other pair consists of sex chromosomes (X, Y). Linked genes are located on the same chromosome; sex-linked genes are located on a sex chromosome. The frequency of crossing-over between genes is used to construct linkage maps, which show the locations of genes on chromosomes.. Many human traits are controlled by a single gene with two alleles as was seen with Mendel’s experiments.. Ex: widow’s peak, dimples, cleft chins, curly hair.. Other traits such as blood type and height may be controlled by many different genes or alleles.. Lectures. . – . 17x2 (Med); . 17x1. (. Stom. ). ;. Seminars. – . 17x3 (Med); . 17x2. (.
