ADVERTISEMENTS:
The upcoming discussion will update you about the differences between Polyteny and Polyploidy.
Difference # Polyteny:
1. Homologous chromosomes undergo somatic pairing.
2. The products of polyteny remain attached to one another.
ADVERTISEMENTS:
3. Polyteny produces hundreds of copies of the same chromosome.
4. Polytene chromosomes are visible in the interphase nucleus.
5. Polytene cells cannot multiply. They are destined to die.
Difference # Polyploidy:
1. Pairing of homologous chromosomes does not occur in somatic cells.
ADVERTISEMENTS:
2. Similar chromosomes remain separate from one another.
3. Polyploidy does not increase in number of chromosomes beyond 6-10 times.
4. Chromosomes are not visible in the interphase nucleus.
5. Polyploid cells behave like normal cells.
