Genetics Warm Up 3

I would like to welcome you to the electronic classroom for biology and life sciences of the 21st century. Today, geneticists rely on Gregory Mendel's work to predict the likely outcome of genetic crosses. This instrument will test your knowledge of vocabulary and principles to solve genetic problems. This warm up permits you an unlimited number of attempts to build up your LEARNING and TEST-TAKING skills. As a bonus, each attempt randomly generates new questions and answers.
