Question

Correct In Cross 1, pure-breeding colored, starchy kernel plants (C1Wx/C1Wx) were crossed to plants pure- breeding for colorless, waxy kernels (c1 wxcl WX) The F1 of this cross were test-crossed to colorless, waxy plants. The test-cross progeny are as follows: Part C Calculate the recombination frequency for cross I. Enter your answer to two decimal places (example 0.12 Phenotype Number Colored, waxy 310 Colored, starchy 858 Colorless, waxy 781 Colorless, starchy 311 Recombination frequency 0.27 Pr 2260 Correct

Explanation / Answer

Recombinant: colored waxy 310          

Non-Recombinant: Coloured Starchy 858             

Non-Recombinant: Colourless waxy 781                               

Recombinant: Colourless starchy 311                    

Total:                                                   2260

There are total recombinant progeny: 310+311=621

Recombinant Frequency = Total number of recombinant progeny/Total number of progeny

Therefore Recombinant frequency = 621/2260

                                                                                = 0.27

So there are 27 percentage recombinant frequency
