In garden peas, the allele for tall plants is dominant over the allele for short plants. a true-breeding tall plant is crossed with a short plant, and one of their offspring is test crossed. out of 20 offspring resulting from the test cross, about should be tall[a] 0[b] 5[c] 10[d] 15[e] 20

The correct option is C)10

The punnet square for the parent cross is shown below:

       t       t

T      Tt    Tt

T      Tt     Tt

The punnet square for the test cross is shown below

         t         t

T       Tt       Tt

t         tt        tt

As 50% of the offsprings will be dominant. Hence, out of 20, 10 will be tall.
