Rising from the sands of the Sonoran desert in 1885, the institution is transforming science fiction into scientific fact, collaborating across disciplines and engaging in novel partnerships to make the unknown known. As one of the world’s premier public research universities, the University conducts more than $625 million of research annually. Home to two allopathic medical schools in Tucson and Phoenix, the UA Tech Park, The University of Arizona Health Network, and a member of the Arizona Space Grant Consortium, the University creates an $8.3 billion economic impact for Arizona.

U.S. News and World Report placed 14 University of Arizona graduate programs among the top 20 in the nation and it is one of the nation’s top producers of Fulbright Scholars.

X-Linked Inheritance

The X and Y-chromosomes that determine the sex of an individual are called allosome*s. Males have one X and one Y-chromosome while females have two X-chromosomes. Due to the differences between the X and Y-chromosomes, the number and type of genes inherited by an individual depends on its sex. The genes present on the X and Y-chromosomes are called sex-linked genes. Sex-linked genes and their related traits are further distinguished as either X-linked or Y-linked depending on which chromosome they are located. Virtual blood typing lab. Punnet Square Flashcards.

Thinking Games. Color Blind Chart. Pattern baldness in men is a sex-influenced trait.

Color Blind Chart

It is not an X-linked trait like color blindness and hemophilia. Baldness is an autosomal trait and is apparently influenced by sex hormones after people reach 30 years of age or older. This condition is inherited as a simple Mendelian trait, although the biochemical mechanism is complex. Quick Trait Calculator - Genetic Heredity Calculator. Note These calculators use simplified models to calculate traits and their certainty is far from 100% due to the fact that human genetics is far more complex than a simple mendelian dominant/recessive model.

Personal Report and Heredity Report give better results, providing that you had your genome sequenced by a commercial personal genomics companies like 23andMe, deCODEMe or Family Tree DNA. In any case, these reports do not substitute for clinical tests, genetic counseling or paternity/maternity tests. If you have questions about your genetic heritage, its relation to diseases or any other health-related issues you should consult your doctor. Alcohol Flush Reaction. Genetics Practice Problems.
