after telophase i of meiosis, the chromosomal makeup of each daughter cell is. … haploid, and the chromosomes are each composed of two chromatids.
What is the chromosomal makeup of daughter cells after telophase 1?
After telophase I of meiosis, the chromosomal makeup of each daughter cell is: haploid, and the chromosomes are each composed of two chromatids.
What is the result of the chromosomes after telophase I?
Telophase I results in the production of two nonidentical daughter cells, each of which has half the number of chromosomes of the original parent cell. Telophase I results in the production of two nonidentical daughter cells, each of which has half the number of chromosomes of the original parent cell.
What is the chromosomal makeup of each daughter cell after telophase II of meiosis?
In this same organism, how many chromosomes will each daughter cell have after telophase II of meiosis? If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
How many daughter cells do you end up with after telophase 1?
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
What is the chromosomal makeup of each daughter cell?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
What happens when pairs of homologous chromosomes separate during anaphase 1?
Figure 3: During anaphase I, the homologous chromosomes are pulled toward opposite poles of the cell. During anaphase I, the microtubules disassemble and contract; this, in turn, separates the homologous chromosomes such that the two chromosomes in each pair are pulled toward opposite ends of the cell (Figure 3).
How many daughter chromosomes are found in each cell after cytokinesis?
Each daughter cell will have 46 daughter chromosomes. Each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell.
How many daughter cells are there by the end of telophase?
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
How many chromosomes did each of the daughter cells contain after mitosis?
At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.
How many replicated chromosomes are in the original cell shown in model 1 during prophase hint when counting chromosomes count 1 for a pair of sister chromatids?
Hint: When counting chromosomes, count “1” for a pair of sister chromacids. Four replicated chromosomes are in the original cell. 7. How many single chromosomes are in each of the new cells in telophase?
What happens in telophase and cytokinesis 2?
In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid.
How many DNA molecules are in the G2 phase?
So no. of DNA molecule in G2 will be =8. No. of chromosome= 4 and as two DNA molecules are held at a common centromere.

How many daughter cells are produced by each of these processes?
They are different four daughter cells each with exactly HALF the number of chromosomes as the parent cell. The purpose of mitosis is to produce two cells with the same number and kind of chromosomes as the parent cell.
How many chromosomes are there after meiosis 2?
During meiosis II, each cell containing 46 chromatids yields two cells, each with 23 chromosomes. Originally, there were two cells that underwent meiosis II; therefore, the result of meiosis II is four cells, each with 23 chromosomes.
How many chromosomes are in each of the cells that you observed?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
