Bruce Wallace (1963) established a laboratory population in which the recessive allele lt was at a frequency of 0.5. He propagated the population for 10 generations, and determined the frequency of lt each generation. a. True
b. False

a. True

Explanation:

Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.

The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.
