In a plant, black seed color (BB/Bb) is dominant over white seed color (bb). In order to find out the genotype of the black seed plant, with which of the following genotype will you cross it?

Options

  1. Abb
  2. BBb
  3. CBB/Bb\mathrm{BB} / \mathrm{Bb}
  4. DBBB B

Correct answer

A. bb

Step-by-step solution

To determine the genotype of a black seed colour at F2F_2, the black seed from F2F_2 is crossed with the white seed colour. This is called a test cross. ∴\therefore To determine the genotype of (BB/Bb)(\mathrm{BB} / \mathrm{Bb}) black seed we need to cross them with white seed i.e. bb.
