Wicked confused about meiosis?

Question

I follow all of the steps but if i'm understanding correctly the 4 daughter cells that are the result of meiosis each onl have one quarter of the original diploid number. I thought they were supposed to end up with 1/2 the diploid number (the haploid number). But from what I'm getting the diploid number is achieved after telophase 1, then after telophase 2 there is another splitting, resulting in the 1/4 number of chromosomes.

Answer 1

I think you forgot the DNA replication phase, where the DNA is replicated, this would require you to double your result of 1/4 to 1/2 the diploid number, and so you have the haploid number which is half the diploid number. I am very very sure you get the haploid number, think about this, If you only had 1/4 the diploid number for one daughter cell, say gametes, then during fertilisation, you would nedd FOUR gametes, which would be absurd. Thus, the daughter cell of meiosis must definitely have 1/2 the diploid number to allow ONE sperm to fertilise ONE egg, which would make sense.

Answer 2

In meiosis, there is 2 STAGES. The 1/2 diploid number is achieved after telophase1. Then of course, it will split up again in stage 2 that's why in telophase 2, the 1/2 is split into two resulting in 1/4 number of chromosomes.

Answer 3

The cell starts with the diploid (2N) chromosome, and undergoes replication to create a tetraploid (4N) cell. In prophase I, the replication is completed, and crossover exchance starts. I noticed that many sources don't indicate this fact well. The four daughter cells have 1/4 of the tetraploid number, N, the haploid number.

Answer 4

During telophase 1, the two daughter cells have half the number of chromosomes but they contain two identical chromatids.

so when they split during telophase 2, they are four cells now each containing a haploid set of chromosomes.

Answer 5

in meiosis, the daughter cells have half the number of chromosomes as compared to the parent cells. that is because in meiosis 1, what happens is that the 46 chromosomes which has 2 chromatids each divide themselves equally (with both pairs of chromosomes represented on each side) to 2 daughter cells thus each would have 23 chromosomes. now in meiosis 2, these 2 daughter cells further subdivide with the chromatids separating from its pair thus the result is 4 daughter cells who have 23 chromosomes with only 1 chromatid

Answer 6

Rat are universally reviled. there have been some sought after mice, Mickey, good and speedy Gonzalez, yet frequently they're pests. the main sought after squirrel, is Rocket J. (Rocky) Squirrel, who with Bullwinkle the Moose, risked existence and liberty enticing in risky counterintelligence paintings against the KGB throughout the chilly conflict. In his advantage, all squirrels are venerated.
