Answer;
petit arm
Explanation;
All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.
The symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.
Well the purple flower is either Bb or BB because it doesn't tell us their offsprings or anything.
Add them all together and divide by how many there are. There are six sunflowers. So add them up and divide by 6. That's your average.
