Genetics and You X-Linked Inheritance Chromosomal Errors (3 films)

Duration: 600 ft.

Year Published: 1977

Complete Record: This film puts the subject of genetics into a more personal perspective for the student. It is designed to be entertaining without compromising the technical information that is presented. Genetics and You (Milner-Fenwick, 1977) covers the key breakthroughs in this field, and illustrates our present understanding of the mechanisms of heredity. X-Linked Inheritance (Milner-Fenwick, 1977) uses color blindness to illustrate inheritance of a recessive gene located in one of the sex chromosomes. Pedigrees illustrate the inheritance pattern for any recessive gene located in the X chromosome. X-linked inheritance is also responsible for such disorders as hemophilia, Duchenes, muscular dystrophy, Vitamin D resistant rickets, etc. Chromosomal Error (Milner-Fenwick, 1977) explores chromosomal development, including meiosis, fertilization, mitosis, and demonstrates how accidents during meiosis lead to garbled genetic messages.
