Based on the results of Experiment 2, which genotype of mice exhibited a significant reduction or complete absence of ultrasonic vocalization when separated from their mother?

  • A: Wild type
  • B: Heterozygote
  • C: Homozygote
  • D: Both Heterozygote and Homozygote

Explanation

Experiment 2 results indicate that wild-type mice produced a high number of whistles 300 , while heterozygotes produced very few 50 , and homozygotes produced none. Therefore, both heterozygous and homozygous mice exhibited a significant reduction or complete absence of vocalization.
