The chromosome number of the pear tree is 68, the quince tree is 34. You will note that 68 = 34 x 2. Does this mean that a pear cell will contain twice the amount of genetic material as a quince tree? Explain?

Not necessarily. It just means that the pear tree has twice as many chromosomes. Chromosomes vary in size, and so the actual amount of genetic material could be the same or even (though very unlikely) less.

No
it means the pear tree has twice as many chromosomes as the quince tree.
If you look at the chromosomes, you will note that they are all of different sizes.
they have different numbers of genes on them
therefore, the quince tree may well have MORE genetic material than the pear tree if its chromosomes are bigger and contain more genes
however, this is probably not the case

Not necessarily. Chromosomes are all different sizes and can have different numbers of genes on them. There may be large areas of nucleotides that do not code for anything. But basically, chromosome number does not equal the amount of genetic material

I pack one suitcase. My girlfriend packs two. Who carries more? (We're liberated and carry our own stuff). You can't answer because my suitcase might weigh 100 pounds full or 5 pounds. Hers may be 20 pounds or 120 pounds (she's buff). The number is not the size. The size is not the infomation.

Yes it does. Unless the cell was tempered with by human technology or interferance.
