What else can I help you with?
Why do you need to count chromosomes during mitosis?
It is possible to count chromosomes only during vell division (mitosis or meiosis). This is because when the cell is not dividing the chromosomes are in an uncoiled, extended state and are not visible under the microscope. During cell division the chromosomes coil up, becoming shorter and thicker and so visible. At this time they can be counted.
What do homologous chromosomes form in pro-phase 1?
Homologous chromosomes pair up during prophase I of meiosis to form a structure called a bivalent, also known as a tetrad. This pairing allows for genetic recombination to occur between homologous chromosomes.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
What role do chromosomes and genes play in determining a child's heredity?
Chromosomes contain genes, which are the units of heredity that determine the traits a child inherits from their parents. Genes carry the instructions for making proteins that control various functions and characteristics in an individual, influencing everything from physical appearance to predisposition to certain diseases. The combination of genes inherited from both parents through their chromosomes determines the unique genetic makeup of a child.
What technique do geneticists use to count and study an individual's chromosome?
Geneticists use a technique called Karyotyping. Scientists take a picture of chromosomes and then arrange them in pairs to end up with 22 chromosomes and another pair that determines sex; chromosome (X,X ) for female or (X,Y) for males. Then you can determine mutation when some chromosomes are missing, ex: missing chromosome 13 will result in Patau Syndrome, or missing chromosome 18 results in Edward's Syndrome
During what phase of mitosis do chromosomes migrate to the equator of the cell and arrange themselves there?
Chromosomes migrate to the equator of the cell and arrange themselves during the metaphase stage of mitosis. This stage occurs after prophase and before anaphase, and is characterized by the alignment of chromosomes in a single plane at the center of the cell.
Explain why prophase is the longest phase in mitosis?
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.

What is the function of a centriole?
Centrioles are only found in animal cells. Their funcion to arrange (or help arrange) the chromosomes in a cell so that the cell can split with an even amount of chromosomes when it reporduces.
What is the plural form of arrange?
There is no plural form for arrange as arrange is verb not a noun.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
How do you arrange on order of importance?
arrange what?????

What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
Homologous pairs of chromosomes line up in the middle of the spindle during meiosis I in the metaphase stage. This alignment is essential for ensuring proper segregation of chromosomes into daughter cells.
What is a prefix for arrange?
A prefix for "arrange" is "re-," as in "rearrange."
All chromosomes except the X and Y sex chromosomes are called?
homologous chromosomes and autosomal chromosomes
