5. Pure-breeding ancient varieties of chickpeas can be black, brown, green, or red in color. A new tan-colored chickpea was isolated and shown to be pure-breeding. To determine the genetic basis of color inheritance in chickpeas, many crosses were made between the various pure-breeding varieties. The results are shown in the table below: Cross Fz offspring Cross F1 F2 offspring phenotype ratio phenotype ratio black X all black 4 black 4 black brown X red all red 3 red 1 brown brown X black all green a green brown X tan all tan tan green X black all black 4 black 4 black green X red all green green red X black all black 4 black 4 black red X tan all black 4 black tan green X tan all green green tan X brown all green 4 green red X tan all pink pink red X green all brown brown pink X tan all green green Analysis of the Fz offspring indicates that a single gene locus determines skin color in chickpeas. B. The mode of inheritance that controls chickpea skin color in the ancient varieties is not specified in the given text. C. The dominance relationship between the alleles of the ancient varieties of chickpea is not specified in the given text. D. The mode of inheritance that controls the new tan chickpea skin color is not specified in the given text. E. The genotypes of the following chickpeas are not specified in the given text: Red = Pink = Tan =
