What is true of meiosis n to n n to 2n 2n to n or 2n to 2n?

Meiosis is a type of cell division that results in the formation of gametes (sperm and egg cells) in sexually-reproducing organisms. The process involves one round of DNA replication followed by two rounds of cell division, producing cells with half the chromosome number (n). This leads to genetic variation and ensures the correct chromosome number is maintained in the offspring.


2n to n?

The relationship 2n to n means that one set has double the elements of the other set. For example, if n=3, then 2n=6, indicating that there are twice as many elements in 2n as in n.


If f(n) n 2 - 2n then f(2) 0. True False?

It is true.


Which phase results in a change of ploidy from diploid 2n to haploid n?

The phase that results in a change of ploidy from diploid 2n to haploid n is meiosis. Meiosis is a type of cell division that occurs in sexually reproducing organisms, resulting in four daughter cells with half the number of chromosomes as the parent cell.


How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?

The alternation of meiosis and fertilization helps maintain the normal chromosome count by ensuring that offspring receive half of their chromosomes from each parent. Meiosis reduces the chromosome number by half, creating haploid gametes, which then fuse during fertilization to restore the original chromosome count in the zygote. This process maintains genetic diversity within a species while also preserving the species' chromosome number.


How does the alternation of Meiosis and fertilization in the life cycle of sexually reproducing organisms maintain normal chromosome count for each species?

Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)


What does n and 2n means?

2N Refers to a diploid cell or organism, in which two copies of each gene are present. Cells before and after mitosis are 2N, or diploid. Cells before meiosis are 2n, and following meiosis are 1n, or haploid.


What value of n will make 256 equals 2n true?

256 = 2n128 = n


How many chromosomes are at the end of meiosis II?

A diploid organism have: 2n chromosome after meiosis 1, the gametes would still have 2n as DNA replication occured Meiosis 1 can be assumed to be the same process as Mitosis. after meiosis 2, the gametes would have n (1/2 of 2n), as the second meiosis would not include any form of DNA replication.


What value of n would make 256 equals 2n true?

256/2 = 128 for n.


What process produce one gamete?

Meiosis. A Diploid (2n) cell splits to form 2 Haploid (n) cells, each are gametes.


Why is meiosis described as a precess of reduction division?

Because the chromosomes are reduced from 2n to n. From diploid( sister chromatids ) to haploid ( one chromosome ).
