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.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
