No, replication only takes place in the S phase of Interphase. Although, a brief interphase exists between Meiosis 1 and Meiosis 2, there is no S-phase in this case. Hence, no replication takes place between meiosis 1 and 2.
because meiosis, unlike mitosis is not about cell duplication. It is about creating gametes which will eventually be combined to form a new organism. These gametes have 1/2 of the cell's chromosomes when meiosis is complete.
niether....DNA is replicated in interphase
False. Chromosome replication occurs during Meiosis I.
No , DNA is not copied or replicated between MI & MII .
Because the purpose of meiosis is to reduce the genetic material in half, so the DNA replicates once, but the nucleus divides twice.
it is replicated in interphase l
no
no
Both Mitosis and Mitosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus. After mitosis, each of the daughter cells will have exactly the same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands, sometime the division is not exactly half and half, but that is not really on the right subject. Because meiosis only has half the information that the parent cell had, the call is unable to reproduce by itself. The reason for meiosis is for reproduction of a multi-cellular organism. One daughter cell, from the male of the sides, will try to find a compatible daughter cell, from the female side, and fertilize it. This then becomes an embryo and the specie has succesessfully reproduced.
In meiosis division: 1 In mitosis division: 2
At the beginning of telophase I, each half of the cell has a complete haploid set of chromosomes, but each chromosome is still composed of two sister chromatids. Cytokinesis usually occurs simultaneously with telophase I, forming two haploid daughter cells. No chromosome replication occurs between the end of meiosis I and the beginning of meiosis II, as the chromosomes are already replicated. In telophase II, the nuclei form and the chromosomes begin decondensing. The meiotic division of one parent cell produces four daughter cells, each with a haploid set of (unreplicated) chromosomes
The answer is more complicated than chromosome number. Offspring of a cross between Przewalski's horse (66 chromosomes) and the domestic horse (64 chromosomes) are trisomic (2n+1) just like mules, mollies and hinnys, yet they are not sterile. The problem is that while horses and donkeys share much of the same genetic information, it is structured differently. Testicular meiosis is arrested in Mules and hinny stallions at the primary spermatocyte stage because of incompatibility of synaptal pairing between paternal and maternal chromosomes.
Hereditary traits are the traits passed from parent to offspring in human reproduction. Eye color, hair color, freckles, nose size, and others are hereditary traits.

In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.

In meiosis 1, the chromosomes were double strand while in meiosis 2, it is single strand.
DNA Replication. Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy
Meiosis I is reductional but meiosis II is equational division .
