Which phase results in a change of ploidy from diploid 2n to haploid n?
The phase that results in a change of ploidy from diploid 2n to haploid n is meiosis. Meiosis is a type of cell division that occurs in sexually reproducing organisms, resulting in four daughter cells with half the number of chromosomes as the parent cell.
Is the end of products of meiosis are haploid cells?
Yes, the end products of meiosis are haploid cells. Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This reduction in chromosome number results in haploid cells.
The ploidy of a cell in Metaphase you is haploid?
In metaphase II, the ploidy of the cell is haploid because it has a single set of chromosomes. This is the result of the separation of sister chromatids in meiosis I, which reduces the chromosome number by half.
What is ploidy reduction?
Ploidy reduction is a process in which the number of sets of chromosomes in a cell is reduced. This can happen during meiosis, the process of cell division that produces gametes (sperm and egg cells) with half the normal number of chromosomes. Ploidy reduction is important for sexual reproduction to maintain the correct chromosome number in the offspring.
What would be the ploidy of the viable gametes produced by a tetraploid individual if nondisjunction of all chromosomes occurred in meiosis you?
The ploidy of the gametes produced by a tetraploid individual with nondisjunction of all chromosomes during meiosis would be diploid. This is because, in nondisjunction, the chromosomes do not separate properly, leading to the formation of gametes with double the normal chromosome number.
What is the ploidy of animal cells that are capable of meiosis?
Animal cells that are capable of meiosis are typically diploid, meaning they have two sets of chromosomes. During meiosis, these diploid cells undergo two rounds of cell division to produce haploid gametes with only one set of chromosomes.
Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis you and meiosis II?
During meiosis I, the DNA content is halved as homologous chromosomes separate, leading to haploid daughter cells. In meiosis II, sister chromatids separate without DNA replication, resulting in four haploid daughter cells with the same DNA content as the parent cell before starting meiosis.
What is another example of cell division besides meiosis ploidy mitosis and endomitosis?
amitosis

Does the ploidy of a cell change when it divides by mitosis Why or why not?
It does not change. Mitosis results in two identical cells with exactly the same number of chromoses. Mitosis occurs in somatic cells for the purpose of growth of tissues, unlike meiosis which occurs in sex cells prior to fertilisation. while mitosis starts and ends as a 2n cell the part about it not changing is wrong. mitosis starts off as 2n then each chromatid replicates creating a 4n cell in prophase until it reaches telophase it goes back to 2n as the chromatids separate at the poles, and the daughter cells are formed.
What is the ploidy of PEN?
PEN, or pollen tube, typically has a haploid ploidy level (n), as it develops from the haploid pollen grain during fertilization in flowering plants. The pollen grain itself originates from the male gametophyte, which undergoes meiosis to produce haploid cells. Therefore, the ploidy of PEN is haploid, containing one set of chromosomes.

What do you start with in meiosis What do you end with?
you start with a cell in interphase and end with a cell that has reproducedthat is not trueYou start with Prophase and end with telophase, or 4 cells (meiotic products)
Are the cells diploid or haploid at the end of meiosis?
At the end of Meiosis II, which is the complete end of Meiosis, you end up with four haploid daughter cells.
