The steps of Meiosis are Interphase, Prophase 1, Metaphase 1, Anaphase 1, telophase 1, Prophase II, Metaphase II, Anaphase II, Telophase II . In other organisms the cells go from the late anaphase of meiosis 1 to metaphase of meiosis II. The second division in Meiosis is simply a mitotic division of the products of meisosis I. It adds a major source of variation among organisms. Variation is important toa species because it is the raw material that forms the basis for evolution.

Steps of Meiosis:

Interphase
ProphaseI
MetaphaseI
AnaphaseI
TelophaseI
ProphaseII
MetaphaseII
Anaphase II
TelophaseII

It is important for living things because it allows the cells to divide and multiply. The new cells have the same number and kind of chromosomes as the origional ones. If we didn't have meiosis then our cells couldn't multiply and we couldn't grow.

The phases of meiois are Interphase, Prophase 1, metaphase 1, anaphase 1, telophase 1. Without metaphase all of the children we have would have defects. The world would be messed up if we didnt have meiosis. By the way this is Jackson my screen name is SMAX

Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2. Meosis is a kind of cell division, it occurs in the specialized body cells of each parent that produce gametes.This allows children to have the same number of chromosomes as their parents.

meiosis is a type of cell division where one body cell produces four gametes, and each containging half the number of chromosomes as a parent's body cell. the steps of meiosis are interphase, phrophas, metaphase, anaphase, and telophase. meiosis is important to living organisms because its what makes new organisms like repoduction.

The steps are interphase, prophase 1, metaphase, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, and telophase 2. Meiosis is a kind of cell division which produces gametes containing half the number of chromosomes as a parent's body cell. Meisosis occurs in teh specialized body cells of each parent that produce gametes.

the steps are interphase prophase 1 metaphase 1 anaphase 1 telophase1 prophase 2 metaphase 2 anaphase2 telophase2. meiosis is what makes us. it keeps the world going round

The phases of meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphse II, Anaphase II, and Telophase II. Meiosis is important because it helps with genetic recombination which causes the gametes to cross and combine. It also explains Mendel's results by showing that Mendel's obsevation of each parent giving one allele at random to offspiring at random.

The phases of meiosis are Interphase, Prophase I, Metaphase II, Anaphase I, TelpphaseI, Prophase II, Metaphase II, AnaphaseII, and Telophase II. This phase is very important becasue this is the phase when the gametes from the parents are produced.

The phases of Meiosis are Interphase, Phropahse 1, Metaphase 1, Anaphase 1, and Telophase 1. Meiosis provides for genetic variation. We need meiosis so we have differnt characteristics.

There are nine steps to Meiosis (1-2). Meiosis 1 is Interphase, Prophase1, Metaphase1, Anaphase1, and Telophase1. Meiosis 2 starts with Prophase2, Metaphase2, Anaphase, and ends with Telophase2.

Meiosis is important because it occurs in the specialized body cells of each parent that produce gametes. Its important in the reproduction of life.

Meiosis has 9 steps. They are Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, Prophase 1, Metaphase 2, Anaphase 2, and Telophase 2. Meiosis is important to organisms because it creates lots of variation between all the organisms throughout the environment. The variation makes the raw material that is used.

The steps of meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II. Meiosis consists of two separate divisions, known as meiosis I and meiosis II. Meiosis I begins with one diploid cell. By the end of meiosis II, there are four haploid cells. These haploids cells are called sex cells or gametes. When a male gametes and female gametes join they create a kid. Meiosis occurs in the specialized body cells of each parent that produce gametes.

the steps of Meiosis are interphase,prophaseI,metaphaseI,anaphaseI,telophaseI
cells of Meoisis is useful for reproduction, helps to parent cells.

Meiosis is the proses for a cell to divid. the steps are Interphase, Prophase, Metaphase, Anaphase, Telophase. It is in portent for thing to grow.

The steps of Meosis are...
(In meosis I)
Interphase
Prophase I
Metaphase I
Anaphase I
Telophase I
(In meosis II)
Prophase II
Metaphase II
Anaphase II
Telophase II

The first generation of meiosis is Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, Prophase 2, Metaphase 2, Anaphase 2, and Telophase 2. It makes everybody different when this process happens. Mendel's laws now explain the theory of heredity.
