Question

A series of experiments shows that starch content in corn is influenced by five genes (a through e) with additive alleles. The highest producing strain is 20% starch content; the lowest has 10%. A plant of unknown genotype has an starch content of 12%. What is a possible genotype for this plant? (+ = additive alleles, - = non-additive alleles) A) a+ a- b- b- c+ c- d- d- e+ e+ B) a+ a- b- b- c- c- d- d- e- e- C) a+ a- b+ b- c+ c- d- d- e- e- D) a+ a+ b- b- c- c- d- d- e- e- A series of experiments shows that starch content in corn is influenced by five genes (a through e) with additive alleles.

Explanation / Answer

C) a+ a- b+ b- c+ c- d- d- e- e- .

In corn starch production is governed by multiple alleles.which means the presence and expression of each gene enhances the starch content of the grain since the plant has 12% starch content the genome should contain more than two genes that enhances the production of starch as they provide additive effect.
