Answer:
True.
Explanation:
There are four phases which occur during karyokinesis, these are -
- Prophase
- Metaphase
- Anaphase
- Telophase
Telophase is the last phase of karyokinesis. The main events that occur during telophase are-
- Uncoiling of chromosome occurs
- Chromatin is formed
- Spindle breaks down
- Nuclear membrane or nuclear envelope if reformed
Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
Answer:
Genetic drift decreases genetic diversity within a population.
Explanation:
Genetic drift decreases genetic diversity within a population. It is a change in allele frequencies due entirely to random chance and is more likely to affect smaller populations than large ones. Population bottlenecks can lead to genetic drift.

(ii) Their life span is short.
(iii) Normally self-pollination occurs but cross-pollination can also be done by artificial means.
(iv) Large no of seeds produced.
