(Problem 12c) In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny:
Porgeny of | Plant A | Pant B |
Dd Pp | 122 | 2 |
Dd pp | 6 | 82 |
dd Pp | 4 | 82 |
dd pp | 124 | 4 |
!!!Please help. I do not know how to tell if this is coupling or repulsion to help me start the problem. please be detailed in your explanation. Thanks in advance.
Explain why different proportions of progeny are produced when plant A and plant B are crossed with the same dwarf pubescent plant.
A. The differences are due to sampling error and are statistically insignificant.
B. Plant A has the two loci in coupling configuration; Plant B has the two loci in repulsion.
C. Plant A has the two loci in repulsion; Plant B has the two loci in coupling configuration.
D. The two plants have different linkage maps for the two genes. E. The two loci are located on a region of the chromosome that has undergone a deletion in plant B compared to plant A.
