The sequence of nitrogen-containing bases on one strand of DNA could determine the a. sequence of nitrogen—containing bases in the Other DNA strand. 1:). sequence of amino acids in protein. c. sequence of nitrogen—containing bases in mRNA. d. All of the above choices are correct. e. sequence of amino acids in the mRNA. 2. A man who carries a harmful sex—linked {on the x chromosome) gene will pass the gene on to: a. All of his daughters 13. Half of his daughters c. Half of hiS‘SODS d, all of his sons e. All of his children 3. If all offspring of a cross have the genotype As, the parents of the crosses would most likely be a. AA x aa. b. As x Aa. c. Aa X as. d. AA x As. e. none of these 4. In Mendel's experiments, if the allele for tall (T) plants was incompletely dominant over the allele for short (t) plants. what offspring would have resulted from crossing two Tt plants? a. 1/4 tall; 1/2 intermediate height; 1/4 short b. 1/2 tall; 1/4 intermediate height; 1/4 short c, 1/4 tall; 1/4 intermediate height; 1/2 short d. All the offspring would have been tall. e. All the offspring would have been of intermediate height. 5.
