In humans, boys get x and y but girls get xx
The spermatocytes which develop into sperm and the oocytes which develop into eggs, also called gametes are only 1N which is half the complement of a fertilized egg/conceptus.

How do you describe how DNA copies itself?
DNA replication occurrs through a process called mitosis. The stages of mitosis are (I)PMAT.InterphaseIn the G1 phase, protein synthesis occurrs and mRNA runs along the chromosomes. In the S phase, DNA polymerase runs along the chromosomes/chromatids and creates complementary strands of DNA. In the G2 phase, the 23 chromosomes all have sister chromatids.2. Prophase- Chromosomes condense, spindle fibers form, and the nuclear membrane disintegrates. (23 chromosomes/46 chromatids)3. Metaphase- the chromosomes line up in the middle of the cell and spindle fibers from the centrioles connect to the chromosomes at the kinetochores. (23 chromosomes/46 chromatids)4. Anaphase- Sister chromatids are pulled apart by the spindle fibers to each pole of the cell. (23 chromosomes/46 chromatids)5. Telophase- nuclear envolopes form around the chromatids at each pole, the spindle fibers reduce, the chromatids decondense. (46 chromosomes/ 46 chromatids)Then cytokinesis occurrs to split up the cell into two cells.
Which part of cell responsible for transmitting genetic disease?
This question doesn't exactly make sense, but I'll try to answer it. The nucleus (or "brain of the cell") contains DNA. DNA is where all genetic makeup is stored. DNA contains chromosomes. Each normal human being has 46 chromosomes. Genetic diseases lie within these chromosomes, pinpointing where they are is the tricky part. A lot genetic diseases have yet to be pinpointed and even when they are pinpointed, finding a cure can be almost impossible without the help of stem cell research.
What process ensures that each daughter cell gets one complete set of genetic information and that each daughter cell has increased surface area?
MITOSIS. Biologists divide the events of mitosis into four phases: prophase, metaphase, anaphase, and telophase. Mitosis insures that each daughter cell has the same genetic information as the parent cell.
How is genetic information passed down from one generation to the next in plants?
Genetic information in plants is passed on from one generation to the next just like in any other living organisms. This is through genes. Genes are parts of the chromosomes whose greater part is the DNA. Through the process of meiosis (which is cell division) the number of chromosomes in a cell is halved. this leads to gametegenesis which is the formation of gametes. each resulting cell with half the number of chromosomes as the original cell carries all the genes.
The genetic structures located within the nucelous of each cell are known as?
The genetic structures located within the nucleolus of each cell are known as chromosomes. These structures are made up of the DNA molecules containing the body's genes.
If you compare the parent cell to the daughter in mitosis what can be said about their chromosomes?
the daughter cells' chromosomes are a identical to the parent cell. they each have a complete set
Normally a complete set of chromosomes is passed to each daughter cell as a result of?
Mitotic cell division.
Number of chromosomes in a normal human body cell - or genome?
In humans there are 23 pairs, for a total of 46 chromosomes (the complete genome) in each body cell.
Why is it important that cellsDNA is duplicated before cell division?
So that each new cell has a complete set of chromosomes containing the DNA.
How many chromosomes does each new cell contains after mitosis if the original cell had 52 original cell chromosomes?
How many chromosomes does each new cell contain after mitosis if the original cell had 52 original cell chromosomes?
How many chromosomes does each new cell contain mitosis if the original cell had 52 original cell chromosomes?
How many chromosomes does each new cell contain after mitosis if the original cell had 52 original cell chromosomes?
How many chromosomes in one cell?
There are 46 chromosomes in each cell
If a cell has 36 chromosomes how many sex cell chromosomes are their?
If their are 36 chromosomes, the sex cells would have 18 chromosomes each.
What cells have a complete set of chromosomes?
All human cells have a complete set of chromosomes. Every single human cell has the same genetic information, but each cell specializes in which information it uses specifically based on the function of the cell.
How many chromosomes will be in each cell after meiosis is completed?
Twenty three chromosomes will be in each cell after meiosis is completed.
How many chromosomes are in each cell after mitosis?
Mitosis produces two cells that have the same number of chromosomes as the original (parent) cell. For example, a human cell has 46 chromosomes - so after mitosis each cell will have 46 chromosomes.
What dose each identical daughter cell have complete after mitosis?
After mitosis followed by cytokinesis, the two identical daughter cells have a complete and identical set of chromosomes, which are the same as the parent cell.
