Question #87248
An agronomist crossed two true breeding Guava plants. One parent is characterized by being Round,terminal,violet and constricted,while the other express the contrasting phenotype of wrinkled,axial,white and full.Assume that the four pairs of contrasting traits are controlled by four genes (R, T, V and C) with each located on a separate chromosome. In the F1 generation, only round, axial,violet and Full were expressed, while in the F2 generation all possible combination of this traits were expressed in ratios consistent with Mendelians inheritance 1)Constitute all the possible phenotypic growth and their frequencies? 2)What is the frequency of the guava plants that will exhibit the dominant trait in only the first 3 loci? 3)what is the frequency of the guava plants that exhibited the dominant traits in only the second(2nd) and fourth(4th) loci? 4)what is the frequency of guava plants that exhibited the dominant traits in the third locus only?
