Q1. A woman with Turner syndrome is found to be color-blind (an X-linked recessive phenotype). Both her mother and her father have normal vision.    a) Explain the simultaneous origin of Turner syndrome and color blindness by the abnormal behavior of chromosomes at meiosis. b) Can your explanation distinguish whether the abnormal chromosome behavior occurred in the father or the mother? c) Can your explanation distinguish whether the abnormal chromosome behavior occurred at the first or second division of meiosis? d) Now assume that a color-blind Klinefelter man has parents with normal vision, and answer parts a, b, and c again.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
