Question

In the F₂ generation, how many of the 16 offspring show round green seeds (dominant for shape, recessive for color)?

Options

• 1

• 3

• 12

• 9

Answer 1

Round green seeds comprise 3 out of 16 F₂ offspring. These offspring have genotypes RRyy or Rryy, expressing the dominant round phenotype (R_) and recessive green phenotype (yy). This represents one of the 3:1 ratio classes in the 9:3:3:1 pattern.
