In meiosis II, what is the primary purpose of the division?
A
To exchange genetic material between homologous chromosomes via crossing over
B
To separate homologous chromosomes and reduce the chromosome number from diploid to haploid
C
To replicate DNA so that each chromosome consists of two sister chromatids
D
To separate sister chromatids into individual chromosomes, producing haploid cells with unduplicated chromosomes
Guida verificata passo dopo passo1
Understand the overall process of meiosis, which consists of two sequential divisions: meiosis I and meiosis II.
Recall that meiosis I is responsible for separating homologous chromosomes, reducing the chromosome number from diploid (2n) to haploid (n).
Recognize that meiosis II resembles a mitotic division where sister chromatids are separated.
Identify that the primary purpose of meiosis II is to separate the sister chromatids of each chromosome into individual chromosomes.
Conclude that this separation results in haploid cells containing unduplicated chromosomes, preparing gametes for fertilization.
