Haploid vs diploid cells

2. Chromosomes contain the genetic information
Chromosomes are made up of DNA
All cells contain chromosomes
Usually chromosomes are in loose strands called
chromatin
However, when DNA is replicated or cells are
ready to divide, the chromosomes tighten and coil
up

3. Every cell has chromosomes
Chromosomes are usually found in pairs
In humans, most body chromosomes are found in
pairs
There are usually 23 pairs of chromosomes
23 pairs equals 46 individual chromosomes
A cell that has 23 pairs (or 46 chromosomes) is a
DIPLOID cell

4. Sex cells are produced by the second division in
Meiosis
Sex cells are NOT diploid cells
Sex cells only have 23 chromosomes
Sex cell have NO pairs of chromosomes
Sex cells are HAPLOID cells

5. Diploid – has pairs of chromosomes
Haploid – has a single set of chromosomes
In humans, diploid cells have 23 pairs of
chromosomes
In humans, haploid cells have 23 chromosomes
(NO PAIRS)

6. Diploid – has pairs of chromosomes
Haploid – has a single set of chromosomes
In humans, diploid cells have 23 pairs of
chromosomes
In humans, haploid cells have 23 chromosomes
