Studying Genetics of Spotting Patterns in Leopard Frogs
What was J. A. Moore investigating in leopard frogs?
J. A. Moore investigated the inheritance of spotting patterns in leopard frogs, specifically the pipiens and burnsi phenotypes.
What were the characteristics of the pipiens and burnsi phenotypes?
The pipiens phenotype had typical leopard frog spots, while the burnsi phenotype lacked spots on its back.
What genotypes were assigned to the parents and progeny in the crosses?
The burnsi allele was designated as [insert symbol], while the pipiens allele was designated as [insert symbol].
What hypothesis needed to be established before conducting a chisquare goodnessoffit test?
Before performing the test, one must establish the hypothesis to be tested by assigning genotypes to the cross's parents and progeny.
Answers:
J. A. Moore studied the genetics of spotting patterns in leopard frogs. The pipiens phenotype possessed the typical leopard frog spots. The burnsi phenotype, on the other hand, lacked spots on its back.
J. A. Moore investigated the genetics of spotting patterns in leopard frogs, focusing on the characteristics of the pipiens and burnsi phenotypes. The pipiens phenotype exhibited the traditional leopard frog spots, while the burnsi phenotype did not have spots on its back.
Moore conducted crosses between the parental phenotypes, resulting in observed progeny with specific phenotypes and genotypes. By assigning genotypes to the parents and progeny in the crosses, hypotheses could be established for further testing using chisquare goodnessoffit tests.
Understanding the genotypes of the parents and how they are inherited by the offspring is crucial in studying the genetics of leopard frog spotting patterns. By designating the burnsi and pipiens alleles with specific symbols, researchers can track the inheritance patterns and test hypotheses through experimentation and analysis.
