The period of growth in between cell divisions is called?
It is interphase, which is divided into three stages. First is a growth stage (G1), during which the synthesis of proteins and other necessary molecules takes place and the cell becomes larger. At about mid-interphase the cell replicates its nuclear DNA (S phase; the letter stands for "synthesis"). Finally there is a second growth stage (G2).
When does the secondary oocyte complete its second meiotic division to become a mature ovum?
The secondary oocyte completes its second meiotic division upon fertilization by a sperm cell. This leads to the formation of a mature ovum and a polar body.
What is the result of the second meiotic division?
Meiosis II results in four haploid (N) daughter cells.
Is disploid the second stage of meiotic division?
No, "disploid" refers to a state where an organism has two sets of chromosomes. Meiotic division is a process that produces gametes with half the number of chromosomes, known as haploid cells. So, disploid is not the second stage of meiotic division.
When chromosomes fail to separate at either the first or second meiotic division this is known as?
When chromosomes fail to separate at either the first or second meiotic division, this is known as nondisjunction. Nondisjunction can lead to the formation of gametes with abnormal chromosome numbers, which can result in genetic disorders like Down syndrome.

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.
When does the secondary oocyte complete its second meiotic division to become a mature ovum?
The secondary oocyte completes its second meiotic division upon fertilization by a sperm cell. This leads to the formation of a mature ovum and a polar body.
What is interkinsis?
Interkinesis is the period between the first and second divisions in meiosis. Meiosis is a special type of cell division of genetic material (DNA). Meiosis produces genetic diversity.
How long is the period of time between your first period and your second period?
28 days
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.
What feature of the chromosome complement is reduced int the first meiotic division and kept equal in the second?
The chromosome number is reduced by half in the first meiotic division, going from diploid to haploid, while the chromosome arms remain the same. In the second meiotic division, the chromosome number remains the same, but the sister chromatids are separated resulting in haploid daughter cells.
How long is the interval between the first and second period and between the third and fourth period?
about 28 days
What is the result of the second meiotic division?
Meiosis II results in four haploid (N) 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.
Is disploid the second stage of meiotic division?
No, "disploid" refers to a state where an organism has two sets of chromosomes. Meiotic division is a process that produces gametes with half the number of chromosomes, known as haploid cells. So, disploid is not the second stage of meiotic division.
