Question 19
XL-RNAT2 marksNeeds review
In garden pea, dwarf plants with terminal flowers are recessive to tall plants with axial flowers. A true-breeding tall plant with axial flowers was crossed with a true-breeding dwarf plant with terminal flowers. The resulting F₁ plants were testcrossed, and the following progeny were obtained:
Tall plants with axial flowers = 320
Dwarf plants with terminal flowers = 318
Tall plants with terminal flowers = 79
Dwarf plants with axial flowers = 83
The map distance between the genes for plant height and flower position is_____cM.
