Right after meiosis I, the homologous chromosomes have separated into different cells. Each homolog carries one copy of the gene, and each gene could be a different allele, but these two homologs are now in two different cells.
What happens to the DNA in meiosis 1?
In meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
What happens to DNA amount after meiosis?
After meiosis I, DNA content gets equally divided into the two cells which means each cell is 30pg. Both the cells undergo further division to form 4 haploid cells during the process of meiosis II. That means the content is further reduced to half i.e 15 pg DNA in each cell(M II).
Does the DNA copy again after meiosis 1?
Meiosis, divided into meiosis I and meiosis II, is a process in which a diploid cell divides itself into four haploid cells. Note that meiosis II immediately follows meiosis I; DNA replication does not occur after meiosis I.
Does meiosis decrease DNA content?
The chromosome number is reduced from 2N to 1N in the first meiotic division, and stays at 1N in the second meiotic division.
What cell is formed after meiosis 1?
However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
