What has happened to the amount of genetic material in a cell after the S phase of interphase?
The amount of genetic material in a cell remains the same after the S phase of interphase. While DNA replication occurs during the S phase, the total amount of genetic material doubles, but the number of chromosomes and the overall genetic content remain constant.
Why is the sporophyte phase diploid?
The sporophyte phase is diploid because it develops from the fusion of two haploid gametes during fertilization, resulting in a zygote with two sets of chromosomes (one from each parent). This diploid organism then undergoes mitotic division to grow and produce spores through meiosis, which are haploid. This life cycle alternates between diploid sporophyte and haploid gametophyte phases, allowing for genetic diversity and adaptation in varying environments.
What is the haploid phase of a mosquito?
The haploid phase of a mosquito occurs during gamete formation (sperm and egg cells). In this phase, the mosquito's cells contain half the number of chromosomes (n) as compared to the diploid phase. When sperm and egg cells fuse during fertilization, they form a diploid zygote.
The phase in which there is a duplication of genetic material is?
The phase in which there is a duplication of genetic material is called the S phase of the cell cycle. During this phase, the DNA in the cell is replicated, ensuring that each daughter cell receives an identical copy of the genetic material.
Spores are produced by what in the diploid phase?
Spores are produced by the sporophyte in the diploid phase of a plant's life cycle through meiosis. The sporophyte is the multicellular, diploid phase of a plant that produces haploid spores as part of its reproductive process. These spores will eventually develop into the gametophyte phase of the plant.

How many chromosomes does a diploid cell in G1 phase have?
A diploid cell in G1 phase has 46 chromosomes.
What does intercalated diploid phase mean?
Intercalated diploid phase refers to a stage in the life cycle of certain organisms, like algae or plants, where the diploid phase is embedded within the haploid phase. This means that after fertilization, the zygote undergoes meiosis to form haploid cells, which then immediately undergo mitosis to form a diploid organism, rather than undergoing immediate differentiation into a distinct diploid phase.
What parts of a moss have diploid cells?
2 sets of chromosomes in their vegetative cells and are said to be diploid, both have the same or similar genetic information.
What is the haploid phase of a mosquito?
The haploid phase of a mosquito occurs during gamete formation (sperm and egg cells). In this phase, the mosquito's cells contain half the number of chromosomes (n) as compared to the diploid phase. When sperm and egg cells fuse during fertilization, they form a diploid zygote.
When does the reduction of chromosomes from the diploid to the haploid number take place?
The reduction of chromosomes from the diploid to the haploid number takes place during meiosis, specifically during the first division called meiosis I. In this phase, homologous chromosomes pair up and exchange genetic material, resulting in the separation of the homologous pairs into different daughter cells.
During which phase of the cell cycle does the replication of genetic material take place?
The replication of genetic material takes place during the S phase of the cell cycle.
What is genetic material called during inter-phase?
chromatin
What genetic material is seen during Ana phase?
chromosomes
The phase in which there is a duplication of genetic material is?
The phase in which there is a duplication of genetic material is called the S phase of the cell cycle. During this phase, the DNA in the cell is replicated, ensuring that each daughter cell receives an identical copy of the genetic material.
During which phase of mitosis does the genetic material replicate?
The genetic material replicates during the S phase of the cell cycle, which occurs before mitosis. This phase is known as DNA synthesis where the chromosomes are duplicated to ensure each daughter cell receives a complete set of genetic material.
