J. A. Moore investigated the inheritance of spotting patterns in leopard frogs. The pipiens phenotype had the normal spots that
give leopard frogs their name. In contrast, the burnsi phenotype lacked spots on its back. Moore carried out the crosses in the
table, producing the progeny indicated. (Moore, 1943).
Cross Parent phenotypes Progeny phenotypes, observed
1
burnsi x burnsi
39 burnsi, 6 pipiens
2
burnsi x pipiens
23 burnsi, 33 pipiens
3
burnsi x pipiens
196 burnsi, 210 pipiens
Step 1: Establish the hypothesis by assigning genotypes to the parents and progeny of the cross.
Before performing a chi-square goodness-of-fit test, you need to establish the hypothesis to be tested.
Hypothesize what the genotypes of the parents are. What genotypes would their progeny have? Define the burnsi allele as B and
the pipiens allele as B*.
