A researcher collected DNA from five dung samples in an elephant population. She amplified the sequence corresponding to the STR locus called "Marker X" and determined each allele's size using gel electrophoresis. The data are shown in the table. Samples that have an identical fragment for both alleles are homozygous for Marker X. If the alleles are different, the individual is heterozygous.

Marker X alleles from 5 dung samples:

null

Which of the lanes shown corresponds to the Marker X profile for this population?

Calculate the frequency for each allele of Marker X (leave your answer as a decimal):

237:

245:
