Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Could crossing over occur during the second meiotic division?
No, crossing over occurs during prophase I of meiosis when homologous chromosomes exchange genetic material. The second meiotic division involves separating sister chromatids, so crossing over does not occur.
How do you identify the meiotic division that occurs in the Lilium anther?
In Lilium anthers, meiotic division can be identified by observing the formation of tetrads of microspores within the anther locules. These tetrads are the result of meiosis, where each microspore undergoes a reduction division to produce haploid cells. By examining the anther tissue under a microscope, the stages of meiotic division can be visualized.
How many meiotic divisions are required in sexual life cycle of pea plant for producing 100 seeds?
Two meiotic divisions are required in the sexual life cycle of a pea plant to produce 100 seeds. The first meiotic division occurs in the formation of pollen grains in the anthers of the flower, while the second meiotic division occurs in the development of ovules in the ovary. Each seed contains genetic material from both the male and female parent, contributing to genetic diversity.
What is more common in humans meiosis or mitosis?
Mitosis occurs in our somatic cells and Meiosis occur in our reproductive cells, gametes Most of the time our body is under the influence of mitosis which replace the old and worn out cells with new one's whereas the Meiotic type of division occurs at a specific time in the life of an organism's development. The chromosome number in mitotic division remains the same whereas in meiotic division the chromosomes number is halved
Meiotic cell division occurs in a special organ known as?
Meiotic cell division occurs in the reproductive organs, such as the ovaries in females and the testes in males.

Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells of humans this extra chromosome occurs in the gamete as a result of?
an error in meiotic cell division
What occurs in mitosis?
In cells during cell division.
During which phase of the meiotic cell cycle does DNA replication occur?
None. DNA replication occurs before meiosis I begins.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.

What sperm is formed during mitosis?
Sperm is not formed during mitosis. Mitosis is a type of cell division that occurs in somatic cells (non-reproductive cells) and produces two genetically identical daughter cells. Sperm formation, known as spermatogenesis, involves meiotic division, which produces four genetically different haploid cells called spermatids that later mature into sperm cells.
This extra chromosome in a gamete occurs as a result of?
This extra chromosome in a gamete occurs as a result of a process called nondisjunction, where chromosomes fail to separate properly during meiosis. As a result, one gamete may end up with an extra chromosome, leading to conditions such as Down syndrome when that gamete contributes to fertilization. Nondisjunction can happen during either the first or second meiotic division and can affect any of the chromosomes.
