What process must a cell undergo to produce genetically different cells?
Answer – Meiosis. A cell must undergo the process of meiosis in order to have genetically different cells at the end of cell division.
What type of cell division produces genetically different cells?
Answer – Meiosis. A cell must undergo the process of meiosis in order to have genetically different cells at the end of cell division. Meiosis produces four daughter (haploid) cells, each of which is genetically distinct from the parent cell from which they arose.
Why must a cell undergo meiosis before cell division?
Answers. A cell must undergo the process of meiosis in order to have genetically different cells at the end of cell division. Meiosis produces four daughter (haploid) cells, each of which is genetically distinct from the parent cell from which they arose.
How many cells are produced at the end of cell division?
Answers. Answer – Meiosis A cell must undergo the process of meiosis in order to have genetically different cells at the end of cell division. Meiosis produces four daughter (haploid) cells, each of which is genetically distinct from the parent cell from which they arose.

Which process must the cell undergo to have genetically different cells at the end of cell division o meiosis?
Mitosis results in cells that are identical to the parent, whereas in meiosis, the daughter cells are gametes with half the genetic material as the parent. In meiosis, cells undergo two rounds of division. In mitosis, they go through one.
Which process must the cell undergo to have genetically different cells at?
When a cell divides it passes genetic information to daughter cells. The amount of genetic information passed on to daughter cells depends on whether the cell undergoes mitosis or meiosis. Mitosis is the most common form of cell division. All somatic cells undergo mitosis, whereas only germ cells undergo meiosis.
Which process can be described as two cell divisions genetic variation?
Meiosis Consists of a Reduction Division and an Equational Division. Two divisions, meiosis I and meiosis II, are required to produce gametes (Figure 3). Meiosis I is a unique cell division that occurs only in germ cells; meiosis II is similar to a mitotic division.
Which process creates cells that are different in the end mitosis or meiosis?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
What is the process of meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
What is the end result of meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Does mitosis create genetic variations?
1 Answer. Meiosis creates more genetic variation. This is because it produces 4 daughter cells, none of which are genetically identical, while mitosis produces 2 identical daughter cells (which are identical to the parent cell).
Where is genetic variation in meiosis?
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Which process creates genetically unique cells?
Meiosis IMeiosis I is responsible for creating genetically unique chromosomes. Sister chromatids pair up with their homologs and exchange genetic material with one another. At the end of this division, one parent cell produces two daughter cells, each carrying one set of sister chromatids. Meiosis II closely resembles mitosis.
What are the two processes in meiosis that create genetic differences among cells?
By the completion of meiotic processes, a diploid cell gives rise to 4 haploid cells (gametes). Meiosis contributes to genetic variation via two important mechanisms, namely independent assortment of gametes and genetic recombination during crossing over.
In which type of reproduction can cells divide through the process of mitosis?
Asexual reproduction relies on a process called mitosis, in which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA.
What is mitosis and meiosis?
Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells (e.g. egg or sperm), each with half the number of chromosomes of the parent cell.
Where do cells come from quizlet?
Where do cells come from? No matter what the cell, all cells come from preexisting cells through the process of cell division.
Do some organisms reproduce by cell division?
Examples of single-celled eukaryotic organisms that reproduce by cell division include algae, some yeasts, and protozoans, such as paramecium. Both unicellular and multicellular organisms can reproduce by budding. Budding is a process in which an organism develops tiny buds on its body.
What is essential for all cellular life as water makes up?
Water allows everything inside cells to have the right shape at the molecular level. As shape is critical for biochemical processes, this is also one of water's most important roles. Figure 2: Water impacts cell shape. Water creates pressure inside the cell that helps it maintain shape.
Which term describes a cell with a full complement of chromosomes 2n )?
Definition. Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body's cells contain 23 chromosomes pairs.

Which process must the cell undergo to have genetically different cells ...
To have genetically different cells at the end of cell division, a cell must undergo MEIOSIS.
Answer
Mitosis. Mitosis is cell division that takes place during the growth of cells. It is such that the genetic material in the parent cell is duplicated by DNA replication and the resultant daughter cells are about exactly thesame. Meiosis on the other hand is cell division that occurs during gamete formation or sexual reproduction.

Why do cells undergo meiosis?
A cell must undergo the process of meiosis in order to have genetically different cells at the end of cell division.
Which phase of meiosis is crossing over?
The correct answer would be crossing over that takes place during prophase 1 of meiosis 1.
What phase does crossing over occur in?
Crossing over of chromatids pair takes place in prophase-I, it is the very first phase of meiosis-1. In this phase, the 3rd subphase is pachytene in which genetic recombination occurs due to the formation of recombinant nodules.
What type of cell joins to form an organism that is genetically identical to the parent?
Haploid cells join to form an organism that is genetically identical to the parent.
What type of cell joins to form an organism that has half the number of chromosomes as the parent?
Haploid cells join to form an organism that has half the number of chromosomes as the parent.
Which type of reproduction produces haploids?
meiosis, part of asexual reproduction because it produces haploids. meiosis, part of sexual reproduction because it produces diploids. mitosis, part of asexual reproduction because it produces diploids.
