An egg can only carry an X chromosome. In normal cases, it only carries one. The sperm carries either one X or one Y chromosome.

Are the chromosome copied before meiosis or during meiosis?
before
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
During meiosis the chromosome number does what?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.

Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
What happens during meiosis that results in a defect characterized by the deletion of a chromosome?

What are the Two strands of chromosome that become visible during meiosis or mitosis?
chromatid
What is it called when a change in the chromosome during meiosis occurs?
This change is know as polyploidy.
During meiosis sex cells form when chromosome pairs are what?
doubled
Why The reduction of the chromosome number during meiosis is most important?
maintaining the chromosome number during sexual reproduction
How does diplonema differ from diakinesis?
Diakinesis is the last stage of prophase during meiosis. Diplonema is the doubled form of the chromosome strand during the diplotene stage of meiosis.
When chromosome pair fail to separate properly during meiosis the error is called?
Nondisjunction.
