How many chromosomes are in the daughter cells after mitosis in cells with 48 chromosomes?

However, during cytokinesis, the cell divides itself into two, meaning that each daughter cell are left with 23 pairs of chromosomes or 46 chromosomes.

How many chromosomes will the daughter cells each have if the parent cell has 46?

Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.

Are there 48 chromosomes in each cell?

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

When a human cell with 46 chromosomes undergoes mitosis the result is?

Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

How many chromosomes are in each daughter cell in 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. Each chromosome consists of 2 sister chromatids.

Are there 92 chromosomes in mitosis?

During metaphase, there are 46 chromosomes composed of two sister chromatids each that align at the metaphase plate. Then, during anaphase, these chromatids are separated and pulled to opposite poles of the cell. This separation results in 92 separate chromatids in the cell, which are considered 92 chromosomes.

What human has 46 chromosomes?

Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

How many chromosomes do parent cells have in meiosis?

Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes (opens in new tab), each have 23 genetically unique chromosomes.

Which of the following is the correct number of chromosomes in 4 daughter cells of human after meiosis II?

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2. How many DNA molecules are present in a chromosome of a cell in metaphase of mitosis?

Can a baby have 48 chromosomes?

This means that a normal sperm cell with one Y chromosome fertilized a normal egg cell with one X chromosome, but right after fertilization nondisjunction of the sex chromosomes caused the embryo to gain two extra sex chromosomes, resulting in a 48,XXYY embryo.

What does having 48 chromosomes mean?

48,XXYY syndrome is a chromosomal condition, characterized by the presence of an extra X and Y chromosome in males, that causes medical and behavioral problems. 48,XXYY can be considered a variant of Klinefelter syndrome.

What is 48,XXYY chromosome disorder?

48,XXYY is one of several types of sex chromosome variations, including those that are considered as variants of Klinefelter Syndrome, 47,XXY and XXXY, XXXXY, XY/XXY and another syndrome called XYY, all of which affect males. Similar female syndromes include Turner Syndrome (XO) and several variations with added X’s.

Are there 92 chromosomes in meiosis?

Meiosis differs in that; during metaphase the chromosomes lie side by side. Then in the anaphase there is no division of the chromatid. The whole chromosome is pulled to the one pole of the cell. The parent cells have 4N (92 chromosomes) and the daughter cells have 2N (46 chromosomes).

What happens anaphase?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

Is parent cell haploid or diploid in mitosis?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

How many parent cells are in mitosis?

In Mitosis, one parent cell divides into 2 daughter cells with identical chromosomal number. However, in Meiosis, one diploid parent cell divides into 4 haploid daughter cells.

How many chromosomes will be found in each cell at the end of anaphase?

At the end of anaphase, there is one cell with 20 chromosomes – 10 chromosomes at one end of the cell, and 10 chromosomes at the other end. Upon completion of telophase and cytokinesis, the single cell will be split into two cells. Each cell will contain 10 chromosomes, the same amount as the original progenitor cell.

Are chromosomes in mitosis a mixture of mother and father chromosomes?

[NOTE: each chromosome is separate. There will almost always be a mix of chromosomes from the mother and father in the entire cell. That is, not ALL the maternal chromosomes will end up on one cell.] In MITOSIS, each daughter cell gets ONE maternal chromosome and ONE paternal chromosome.

Do we have 46 chromosomes or chromatids?

As a cell prepares to enter meiosis, each of its chromosomes has duplicated in the synthesis stage (S) of the cell cycle, as in mitosis. Each chromosome thus consists of two sister chromatids. At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis).

How many chromosomes are present at anaphase If a cell contains 16 chromosomes at the start of mitosis?

During anaphase, we now have a total of 16 chromosomes and 16 chromatids – in short, each chromatid is now a chromosome. Similarly, in humans, there are 92 chromosomes present and 92 chromatids during anaphase.

What are the 23 human chromosomes?

Humans have 23 pairs of chromosomes–22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.

What is chromosome 23?

The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female.

How many chromosomes do you get from each parent?

Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
