Group of answer choices   A) Add functional bicoid protein to the head end of a wildtype larva B) Add functional bicoid protein to the tail end of a mutant larva C)Add functional bicoid protein to the tail end of a wildtype larva D)Add bicoid protein from a mutant fly to the tail end of a wildtype larva

84. Neurobiology of speech and language has been studied in a family in which half of the members have severe impairment in both speech and language. The mutation responsible for the phenotype was identified in the FOXP2 gene. In addition, this gene is found on a chromosome segment tightly linked to autism, a disorder in which language is impaired. How would you directly test the hypothesis that this gene is necessary for vocal communication in other mammals? a. Use molecular genetic techniques to disrupt (inactivate) the mouse Foxp2 gene and observe the effect on ultrasonic vocalizations in the knockout mice. b. Determine the DNA sequence of the FOXP2 gene in several species of mammals that communicate vocally and compare these sequences to the DNA sequence for the human gene to determine whether the gene is evolutionarily conserved. c. Compare neural expression patterns of the FOXP2 gene between species that communicate vocally and related species that do not communicate vocally to…
