Problem:

Strain 1: the frogs have purple eyes and croak by uttering "rib? it rib? it" (utterers)

Strain 2: the frogs have green eyes and croak by muttering "knee? Deep knee-deep"(mutterers)

She mated frogs from the two lines, producing F1 frogs that were all utterers with blue eyes. A large F2 generation then yielded the following ratio:

27/64 blue, utterers

12/64 green, utterers

9/64 blue, mutterers

9/64 purple, utterers

4/64 green, mutterers

3/64 purple, mutterers

Question: How many total gene pairs are involved in the inheritance of both eye colour and croaking? Justify your answer.

Question: Of these, how many control eye colour and how many control croaking?BIOL 2341: Introduction to Genetics A4-9 TRU Open Learning

Question: Assign gene symbols for all the gene pairs and give the genotypes of the Parental, F1 and the genotypes for all of the six F2 phenotypes.

Question:   After many years, the geneticist isolated true? Breeding lines of all six F2 phenotypes. Give the F1 and F2 phenotypic ratios of a cross between a blue, mutterer and a purple, utterer.

Please explain the answer of following questions.
