ANSWERS


In soybeans, dwarf (D) is dominant to tall (d), round (R) is dominant to oval (r), and
green (G) is dominant to brown (g). The genes are linked and the map is given below.
Pure-breeding tall, oval, brown plants were mated to pure-breeding dwarf, round, green
plants. The F1 were testcrossed. All loci are autosomal. The coefficient of coincidence
is 1.
Height-------14cM-------Shape-------22cM-------Color
Rank the progeny phenotypes below to indicate their frequency in the testcross progeny
based on the data above. Use 1 to indicate the most frequent then 2, then 3 and let 4
indicate the least frequent.
