A tetrad is the pairing of homologous chromosomes. A human offspring inherits 23 chromosomes (N) from each parent upon fertilization, giving the offspring 46 chromosomes (2N). In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologous chromosomes. Since you inherit a chromosome from both parents (2N) that pair up to form a tetrad, you will have 23 tetrads that have a chromosome from mom and dad paired together.
1 N from mom + 1 N from dad = homologous pair = 1 tetrad
2N/2 = N tetrad --humans--> 2(23 chromosomes)/2 = 23 tetrads
Diploid#/2 = # tetrad

What is mitosis How many new cells are formed and how many chromosomes are in each newly formed cell?
Mitosis is a kind of cell division, where a parent cell splits into two identical daughter cells. Two cells are created during mitosis, but the original cell no longer exists so the total number will go up by one (or, if you're looking at multiple cells, the total number will double). The new cells have the same number of chromosomes as the original cell before it divided.
Do human use mitosis or miosis?
Humans use both- mitosis to grow, meiosis to form sex cells for reproduction.
When do we have 46 chromosomes in meiosis or mitosis?
we have 46 chromosomes in Mitosis during interphase when the DNA doubles, but really Humans have 23 chromosomes. Meiosis is reproduction and goes through Mitosis twice but skips interphase the second time and creates gametes(sex cells) -Marina20
When your cell undergo mitosis how many chromosomes do the new daughter cells have?
46.In humans, the only cells that divide by mitosis are ones with two sets of chromosomes, called diploid cells. They have 46 chromosomes, and the daughter-cells have 46 as well, because mitosis preserves the chromosome number.
How does the cell cycle differ from the human life cycle?
Cells replicate themselves and eventually part during mitosis. Humans reproduce when the female egg cells is fertilized by the male sex cell.
How many chromsomes will be in the new body cells formed from mitosis?
46 in humans
During anaphase of mitosis in humans do the chromosomes have one or two chromotids?
they have one
What is mitosis How many new cells are formed and how many chromosomes are in each newly formed cell?

The new cells have the same number of chromosomes as the original cell before it divided.
How many cells do humans have after mitosis?
double what the person already had if mitosis is when cells divide into two cells
Mitosis in humans results in the formation of what?
Mitosis in humans results in the formation of two genetically identical daughter cells, each with the same number of chromosomes as the parent cell. This process is essential for growth, repair, and asexual reproduction in organisms.
Does mitosis occur in humans?
Yes, mitosis occurs in humans. It is a process of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell.
Do human use mitosis or miosis?
Humans use both- mitosis to grow, meiosis to form sex cells for reproduction.
How many chromosones are visible at the beginning of mitosis?
These answers are, well, misguided. The number of chromosomes visible at the beginning of mitosis is whatever the full complement of chromosomes is for that organism. In humans, it would be 46. As mitosis proceeds, these are replicated to 92, but at the very beginning of mitosis you would still have the diploid number.
When do we have 46 chromosomes in meiosis or mitosis?
we have 46 chromosomes in Mitosis during interphase when the DNA doubles, but really Humans have 23 chromosomes. Meiosis is reproduction and goes through Mitosis twice but skips interphase the second time and creates gametes(sex cells) -Marina20
What is formed in the final phase of mitosis?
A pair of diploid Cells - each Cell has a full number of chromosomes like most body Cells. For example, humans have 46 chromosomes in almost every body Cell. After mitosis, the daughter Cells will also have 46 chromosomes. Two Daughter Cells.
What is mitosis involved in?
Nearly all eukaryotic cells go through mitosis to divide. Being more specific: in humans, somatic (body) cells go through mitosis.
What type of cells divide by mitosis?
somatic cells are generally in humans
