DNA is copied during **interphase**. This phase occurs before meiosis begins and involves the replication of DNA, ensuring that each daughter cell will have a complete set of chromosomes after meiosis is complete.

Why is it important for gametes to be haploid?(1 point)
Responses
When gametes are made, the diploid cell splits twice, creating four haploid organisms.
When gametes are made, the diploid cell splits twice, creating four haploid organisms.
It is impossible for them to be diploid because reproduction does not result in diploidy.
It is impossible for them to be diploid because reproduction does not result in diploidy.
Neither parent has the full set of genetic information so each must contribute their half.
Neither parent has the full set of genetic information so each must contribute their half.
They fuse to form a diploid organism so that there is the expected number of chromosomes.

The correct response is: **They fuse to form a diploid organism so that there is the expected number of chromosomes.**
This is important because gametes are haploid (having half the number of chromosomes) so that when they fuse during fertilization, the resulting zygote is diploid and contains the correct number of chromosomes for the species.

GPT-4o mini
The correct response is: **independent assortment.**
Independent assortment refers to the principle that the inheritance of one gene does not influence the inheritance of another gene when genes are located on different chromosomes or are far apart on the same chromosome.

Which of the following is a difference between phase I and phase II of meiosis?(1 point)
Responses
Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.
Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.
Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
Genetic variations can only occur during phase II of meiosis.
Genetic variations can only occur during phase II of meiosis.
Anaphase, metaphase, and telophase only occurs during phase I of meiosis.

The correct response is: **Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.**
Meiosis consists of two successive divisions: meiosis I and meiosis II. Meiosis I results in two haploid cells, while meiosis II divides those haploid cells to produce a total of four haploid daughter cells.

The correct response is: **crossing-over.**
Crossing-over is the process during meiosis where non-sister chromatids exchange segments of DNA, leading to increased genetic diversity among the resulting gametes.
