Examples: Eye color, basketball skills. A regular human cell has 46 chromosomes: 44 autosomes, which come in pairs, and 2 sex chromosomes, which specify gender (XX for female and XY for male).. The pairs of autosomes are called "homologous chromosomes." One of each pair came from mom and the other came from dad. Homologous chromosomes have all of the same genes arranged in the same order, but with slight differences in the DNA sequences of the genes.. Two copies of each autosomal gene affect phenotype.. Mendel studied autosomal gene traits, like hair texture. . Mendel. ’. s rules of inheritance apply to autosomal genetic disorders.. A heterozygote for a recessive disorder is a carrier. . (And why was his work so important?). Gregor. Mendel. Gregor. Mendel was a monk who lived in the 1800s. Mendel’s Mind Wandered…. Mendel wondered how the same species of plants could have different characteristics. 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.. Gregory D. S. Anderson.
