How does a haploid gamete get a 1n number of chromosomes and a 1n amount of DNA?
By the process of meiosis.
What is the medical term meaning abnormal condition of meiosis?
Nondisjunction is the medical term meaning abnormal condition of meiosis. For example, trisomy 21 (Down syndrome) is a nondisjunction.
What is the function of the cells made from meiosis?
The product of meiosis are sex cells or gametes 1N, Eggs, Sperm and pollen. Because of meiosis, and crossing over, these cells are genetically unique. Consequently, the union of these sex cells (egg and sperm) form new and different combinations and therefore allow for variation and change within a species.
The chromosome number after meiosis is denoted as?
Multiply the diploids by the haploids and divide by 2 to get the chromosome number.
What are two parts of cell division?
Mitosis and Cytokinesis
How does a haploid gamete get a 1n number of chromosomes and a 1n amount of DNA?
By the process of meiosis.
Why does meiosis result 1N cells rather than 2N cells?
During meiosis chromosomes are segregated at Anaphase I stage , this results in reduction in number of chromosomes from 2N to 1N .
Which type of cell is formed during meiosis?
1N Gametes.
If a organisms has 500 chromosomes how many will be present in each cell through process meiosis?
250 would be the 1N number after meiosis.
How many haploid sperm cells have been formed after the meiosis process?
i learned in science class that 4 sperm cells ((aka 1n)and 1n means hapliod) are formed after meiosis. In a female reproductive system, only one is formed.
How many chromosomes does a sperm cell have at prophase I?
Sperm are all 1N (half the complement of chromosomes of the original male). Prophase 1 in meiosis the cell is 4N Prophase 2 in meiosis the cells are 2N Final division creates 1N cells.
How many chromosomes are there in each cell at the end of meiosis?
1N or half of the original 2N count of the organism in question.
What kinds of cells are produces from meiosis?
Meiosis is a special kind of cell division that produces haploid (1n) cells. During meiosis, a single cell goes through two cell divisions (meiosis I and meiosis II.) Meiosis takes place only in the reproductive tissues of an organism.
What is meiosis?
Division of cells in which four "daughter" cells are produced from one "parent" cell, each with half the genes of the parent. Meiosis is a special kind of cell division that produces haploid (1n) cells. yah
Is there a difference in the the two stages of meiosis?
Yes. The main difference is that DNA replicates before Mieosis I, but not before Mieosis II. For example, human cells are almost always diploid (2n). Before Mieosis I, the DNA doubles, resulting in a 4n cell. After Meiosis I, there are two 2n cells. Then Meoisis II occurs, without any DNA replication, to form a 1n cells. In humans, the 1n cells are eggs and sperm. When one egg (1n) and one sperm (1n) fuse, a normal 2n zygote is formed. Without this intricate system, repdroduction wod not occur as we know it.
How are the gametes produced by meiosis alike?
They are all 1N (haploid) and they all come from the same individual (assuming the question is regarding the gametes produced by a single individual).
What is the medical term meaning abnormal condition of meiosis?
Nondisjunction is the medical term meaning abnormal condition of meiosis. For example, trisomy 21 (Down syndrome) is a nondisjunction.
