A man has a disease that causes a thyroid disorder. To stop this disorder from being passed to his children, the faulty gene would have to be repaired in the mothers a. blood cells b. thyroid cells c. gamete cells d. somatic cells 77. What is an autosome? a. sex chromosomes b. chromosomal pairs 1-22 c. the X and Y chromosomes d. how you tell the sex of an organism 78 79. Natural selection acts on the diversity in and among species by a. Ensuring that only organisms that are fittest and best adapted to their environment survive and reproduce. b. Ensuring that only organisms that show no variation from other members of their population survive and reproduce. c. Acting only on mutations that are not carried in an organism’s genes. d. Favoring organisms that produce large numbers of genetically offspring. 80. A paleontologist is comparing the fossilized remains of 2 primates. Both animals had a prehensile tail (a tail that can grip like a hand). What can be concluded from this evidence? a. They are not related. b. They lived on the ground. c. They evolved from a common ancestor. d. They had bipedal locomotion. 81. Which could be considered biomolecular evidence of an evolutionary relationship? a. absence of vestigial structures b. presence of embryonic gill slits c. similar anatomical structures d. presence of identical proteins 82. A particular allele in mice is lethal in homozygotes. Heterozygotes, however, develop normally. Why does this allele remain in the population? a. Homozygous mice pass the allele to their offspring. b. The recessive allele is masked in heterozygotes. c. Natural selection selects for the homozygous individual for normal alleles. d. Natural selection selects against the heterozygous individual.
