  3. answer c, of two different phenotypes

  4. Its question answer c. I believe.

    Take Bb bb for example.

    Cross that into four grids and carry over the letters accordingly. There is a 50% chance that the offspring will hold the recessive trait. So there is a 50% chance that the offspring will hold the heterozygous form as well, since big letter in front of little letter still passes off as dominant.
