A. What is the dipolid number of chromosomes?
B. What is the 2N number of chromosomes?
C. How many autosomes?
D. How many sex chromosomes?
E. How many chromosomes are from the father?
F. What is the haploid number of chromosomes?
G. What is the 1N number of chromosomes?
H. How many autosomes are present in an armadillo egg cell?
I. How many sex chromosomes are present in an armadillo sperm cell?
Thanks in advance. I know some of these questions are repetitive and will have the same answer, just want to make sure they are correct.

A. Is 64. Armadillos and therefore diploid i.e. they have 2 full sets of chromosomes one from each parent.
B Is 64.2n is the same as diploid
C. 64-2 = 62 autosomes.
D.2 either XX or XY
E, half i.e. 32
F. 32, eggs and sperm are haploid gametes that fuse to make a diploid organism.
G. 32, 1n = haploid.
H. 31
I 1 X or Y.

The diploid number is the normal number of chromosomes for that species, so A=64.
The 2N number (in mitosis) is 128 (twice the normal number)
Autosomes refer to any chromosomes that are not sex chromosomes, so the answer is 62.
Naturally, the armadillo will then have 2 sex chromosomes, either XX or XY depending on gender.
Half of the chromosomes are from the father, or 32.
The haploid number is also 32; this is half of the normal number (64) which happens in meiosis, or the making of sperm or eggs (gametes)
The 1N number is 64; this is just another way to say the diploid number.
Your teacher is trying to be tricky with the last two, but we've got this, no problem!
In either an egg or sperm cell, there will be half of the normal number of chromosomes so when fertilization happens, the new armadillo will have the normal number of chromosomes in each cell. Autosomes, remember, are all of the chromosomes except sex chromosomes, so in the egg (OR sperm), there will be 31 autosomes, and in the sperm (OR egg) there will be one sex chromosome.
