What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
Describe the differences between the original cell that undergoes meiosis and the daughter cells produced by meiosis?
The original cell that undergoes meiosis is diploid, meaning it has two sets of chromosomes. The daughter cells produced by meiosis are haploid, containing only one set of chromosomes. Additionally, the original cell undergoes two rounds of cell division to produce four daughter cells, each genetically unique due to crossing over and independent assortment.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What are the phases of meosis?
Meiosis consists of two main phases: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, resulting in two haploid daughter cells. Meiosis II involves the separation of sister chromatids, producing a total of four haploid daughter cells with unique genetic combinations.
How does meiosis produce haploid gametes?
Meiosis is a cell division process that reduces the chromosome number by half, resulting in the production of haploid gametes. It involves two rounds of cell division, meiosis I and meiosis II, which separate homologous chromosomes and sister chromatids to create four genetically different haploid cells.
What is the difference in DNA between parent cells and daughter cells in meiosis?
Parent cells are diploids, and daughter cells are haploids. Therefore, the daughter cells have half of the the number of chromosomes as the parent cells. (chromosomes are DNA)
Difference in DNA between parent cell and daughter cell in meiosis?
Homologous chromosomes assort independently, so each gamete has a unique combination of alleles
What is result of meiosis 2?
NovaNet/GradPoint answer: four haploid daughter cellsMeiosis 2 creates a total of 4 haploid daughter cells from an original 2 daughter cells (created during meiosis 1). Each daughter cell has a completely different set of DNA than the 2 daughter cells created in meiosis 1, as well as the original parent cells.
Is the result of meiosis 2?
NovaNet/GradPoint answer: four haploid daughter cellsMeiosis 2 creates a total of 4 haploid daughter cells from an original 2 daughter cells (created during meiosis 1). Each daughter cell has a completely different set of DNA than the 2 daughter cells created in meiosis 1, as well as the original parent cells.
Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis you and meiosis II?
During meiosis I, the DNA content is halved as homologous chromosomes separate, leading to haploid daughter cells. In meiosis II, sister chromatids separate without DNA replication, resulting in four haploid daughter cells with the same DNA content as the parent cell before starting meiosis.
What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.

What are the names of the cells that meiosis produces?
Meiosis produces gametes, which are reproductive cells such as sperm and egg cells.
Is the parent cell diploid a characteristic of meiosis not mitosis?
Yes, the parent cell in meiosis is diploid because it undergoes DNA replication before entering meiosis, resulting in two copies of each chromosome. In mitosis, the parent cell is also diploid but does not undergo DNA replication specifically for the purpose of meiosis.
What are the phases of meosis?
Meiosis consists of two main phases: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, resulting in two haploid daughter cells. Meiosis II involves the separation of sister chromatids, producing a total of four haploid daughter cells with unique genetic combinations.
