With the left hand, a person grabs a handful of tomato seeds that vary genetically from a bag and plants the seeds in a pot. With the right hand, this person grabs seeds from the same bag and plants them in a second pot. The first pot has enriched soil and exposure to sunlight, whereas the nutrients in the second pot's soil have been depleted and the pot is placed in a dark corner. When the tomato plants grow:
A) the heritability of between-pot differences is 100% but the heritability of within-pot differences is 50%.
B) the differences within each pot are due to environment but the heritability of between-pot differences is 100%.
C) the difference between pots is due to variations in soil and sunlight but the heritability of within-pot differences is 100%.
D) the heritability of between-pot differences and within-pot differences are equal, ranging from 50% to 60%.

The differences between pots are due to environmental factors (soil and sunlight), while the genetic variation within each pot is responsible for differences, making the heritability of within-pot differences 100%.
