Anaphase is a critical stage of cell division, specifically during mitosis and meiosis, where sister chromatids or homologous chromosomes are pulled apart to opposite poles of the cell. This separation ensures that each daughter cell receives the correct number of chromosomes, maintaining the organism's ploidy level. In mitosis, the ploidy remains unchanged, resulting in two diploid daughter cells, while in meiosis, the reduction of chromosome number leads to haploid gametes, crucial for sexual reproduction. Thus, anaphase plays a vital role in ensuring genetic stability and variation within an organism's life cycle.

Is a change in ploidy always harmful to an organism?
A change in ploidy is not always harmful to an organism; it can sometimes be beneficial or neutral. For example, polyploidy, which is the condition of having more than two sets of chromosomes, is common in plants and can lead to increased vigor and adaptability. In some cases, organisms can tolerate or even thrive with changes in ploidy, while in others, it may disrupt normal development and function. Thus, the effects of ploidy changes depend on the specific organism and context.
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.

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.
What is the ploidy of a embryo?
2n
What is ploidy of the endosperm?
3n
What is ploidy number?
Ploidy number refers to the number of complete sets of chromosomes in a cell. In humans, for example, the typical ploidy number is diploid (2n), meaning there are two sets of chromosomes, one inherited from each parent. Certain organisms or specific cells can be haploid (1n), with one set of chromosomes, or polyploid, having more than two sets. Ploidy plays a crucial role in genetics, influencing traits and the organism's overall biology.
What is camelina sativa ploidy?
Its Hexaploid
What is the ploidy of mammal gametes?
Haploid (n)
What are haploid cells also known as?
Ploidy
What is the ploidy level of body cells?
23
What is the ploidy of the zygote produced by fertilization?
2n
A zygote possesses what ploidy level?
A zygote is a diploid
What is the ploidy of cells?
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
