Question

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 is1. Height Shape Color 14cM 22cM 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. tall, round, brown Choose. tall, round, green Choose.. tall, oval, brown tall, oval, green Choose.... Choose... +

Explanation / Answer

Mating of dRG x Drg takes place and forms the F1 generation

Tall, round, brown -----------> 1

Tall, round, green --------------> 2

Tall, oval, brown ---------------> 4

Tall, oval, green --------------> 3
