3. You have in your possession a microscope slide with meiotic cells on it and a light microscope. What would you look for if you wanted to identify metaphase I cells on the slide? A) a visible nuclear envelope B) separated sister chromatids at each pole of the cell C) tetrads lined up at the center of the cell D) an equal number of centromeres and chromosome arms E) a cleavage furrow 5. Which of the following statements about Mendel's dihybrid experiments is correct? A) None of the parental (P) plants were true-breeding. B) All of the F2 progeny showed a phenotype that was intermediate between the two parental (P) phenotypes. C) Half of the F1 progeny had the same phenotype as one of the parental (P) plants, and the other half had the same phenotype as the other parent. D) All of the F1 progeny resembled one of the parental (P) plants, but only some of the F2 progeny did. E) None of the above 8. If proteins were composed of only 12 different kinds of amino acids, what would be the smallest possible codon size in a genetic system with four different nucleotides? A) 1 B) 2 C) 3 D) 4 E) 12 10. Which modification of the sentence THECATATETHERAT is analogous to a frameshift mutation? A. THERATATETHECAT B. THETACATETHERAT C. THECATARETHERAT D. THECATATTHERAT E. CATATETHERAT 12. Hypophosphatemia (vitamin D-resistant rickets) is inherited as a X-linked dominant disorder. An unaffected woman mates with a male with hypophosphatemia. What is the expected phenotypic ratio of their offspring? A) 1 normal daughter: 1 daughter with hypophosphatemia B) 1 normal daughter : 1 son with hypophosphatemia C) 1 daughter with hypophosphatemia : 1 normal son D) 2 normal daughters : 1 normal son : 1 son with hypophosphatemia E) 3 normal daughters : 1 son with hypophosphatemia 18.In birds, sex is determined by a ZW chromosome scheme. Males are ZZ and females are ZW. A lethal recessive allele that causes death of the embryo is sometimes present on the Z chromosome in pigeons. What would be the sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a normal female? A) 2:1 male to female B) 1:2 male to female C) 1:1 male to female D) 4:3 male to female E) 3:1 male to female
