Why is it important for gametes to be haploid?(1 point)
Responses
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.
It is impossible for them to be diploid because reproduction does not result in diploidy.

They fuse to form a diploid organism so that there is the expected number of chromosomes.
They fuse to form a diploid organism so that there is the expected number of chromosomes.
When gametes are made, the diploid cell splits twice, creating four haploid organisms.
- Each of the four haploid cells contains a unique combination of genetic information, increasing genetic diversity within the species.
- Haploid gametes fuse during fertilization to restore the diploid number of chromosomes in the resulting organism.
- Haploid gametes prevent the doubling of genetic material with each generation, maintaining a stable number of chromosomes in the species.
I need an answer of the one i gave you
The answer you provided is:
- Neither parent has the full set of genetic information, so each must contribute their half.
This is a correct answer for why it is important for gametes to be haploid. Haploid gametes ensure that each parent contributes an equal and balanced amount of genetic information to the offspring.

Which of the following is a difference between phase I and phase II of meiosis?(1 point)
Responses
Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
