8 In pea plants purple P flower color is dominant to white p flowers and yellow Y seeds are dominant to green y seeds Flower color and seed color are inherited independently A cross is done between two plants of unknown genotypes and the results of the F1 generation are analyzed Purple yellow 0 Purple green Purple yellow 0 155 You notice right away that all offspring are white You then notice that the yellow green ratio is approximately 3 1 Knowing this determine the parental genotypes White yellow I 9 A second cross is done between two plants of unknown genotypes following the same traits as in problem 8 The results of the F1 generation are in the table below Purple green 321 146 Show work here Py PY py py Py Pypy PyPy pypy pypy Whitesgroen By By PY PYPY by PY PYPY 101 White yellow 52 White green 49 The results for this appear to be more complicated but you know that the ratios between purple white flowers and yellow green seeds are the key to solving the parental genotypes Use problem 8 to help you if you get stuck py Pypy Pypy pypy pley by Tryp YLPYPY HEAR YpYp Ple Show work here pY4y
