PPT-Human Quantitative Traits

By Francesco Bartucci and Adnan Sator What are Human Quantitative Traits A human q uantitative t rait is a measureable trait that shows a continuous variation and can have numerical values that can be ordered from highest to lowest.

Explains why organisms have certain traits . How traits are passed from parent to offspring. The most well-known and medically important blood types are in the ABO group. . All humans and many other primates can be typed for the ABO blood group. . There are four principal types: A, B, AB, and O. . Describe the role and importance of genetics in the animal industry. Recognize & describe the interrelationship between genetics and the environment. Identify common characteristics used to select high quality breeding stock. Genes in populations. Gene and genotype frequencies. Hardy-Weinberg . equilibrium. Linkage . disequilibrium. Descriptive statistics for quantitative traits. Genetic variance. Heritability. Relationships among relatives. 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.. quali. . tative. traits are the classical Mendelian traits of kinds such as form (e.g., round or wrinkled seeds of pea); structure e.g., horned or hornless condition in . cattles. ) ; pigments (. e.g.,black.
