Test your "GQ" (genetics quotient)! 1. Type A blood is dominant to Type O blood. Is it possible for a man and a woman, each with Type A blood, to have a child that is Type O? Yes, if the man is heterozygous Yes, if the woman is heterozygous Yes, if both parents are heterozygous No, it is impossible 2. According to Mendel, the traits observed in offspring result from a blending of parental traits. Therefore, a tall pea plant crossed with a short pea plant will produce a pea plant of intermediate height. True False 3. In cells, long pieces of DNA are organized into individual units called- microtubules RNA nuclei chromosomes 4. Down Syndrome results from- an extra copy of chromosome 21 a missing copy of chromosome 21 a specific gene mutation negative environmental exposures during gestation (such as to drugs, alcohol or cigarette smoke) 5. During traditional genetic testing, an individual's entire genome is sequenced. True False 6. Recombinant DNA technology has been used to- create bacteria that produce human insulin make mice that glow fluorescent green generate rice that appears yellow in color because it produces beta carotene all of the above 7. DNA is made up of repeating subunits called- RNA nucleotides genes bases 8. In the United States, it is currently legal to patent genes. True False 9. Which of the following concerns about GM (genetically modified) crops has come true? Consumers have experienced allergic reactions. Genes from GM crops have spread widely to non-GM crops. There is a positive correlation between cancer rates and GM food consumption. "Superweeds" that are resistant to pesticides have developed. 10. The DNA in the skin cells of your hand is significantly different in sequence from the DNA in your liver cells. True False Be sure to click Submit Quiz to see your results! Time's up
