Diploid cells are reduced by 1/2
100
Daughter cells produced by mitosis are ______ to the parent cell
identical
100
An individuals complete set of chromosomes arranged in numerical order
What is a Karyotype?
100
Two chromosomes that are the same size, carry the same genes, and look the same under the microscope but have some minor base differences in their comparative DNA code.
What are a Homologous pair
same "recipe" but minor differences in their genes.
100
The main event in meiosis 1
the homologous pairs are lined up in pairs and are being pulled apart by spindle fibers
200
In mitosis, a body cell produces two identical body cells. How is meiosis different? 1. body cell is doubled 2. it starts with a body cell and produces 4 gametes
2. It starts with a body cell and produces 4 gametes
200
The first step in the mitosis process
duplicating DNA
if you said duplicating organelles you are also correct
200
A _______ cell is the kind of cell meiosis begins with? 1. haploid 2. diploid
What is 2. diploid
200
Half the total amount of chromosomes
A. Haploid B. Diploid
A. Haploid
200
An organism has 62 chromosomes. After completion of meiosis, how many chromosomes will the gametes contain?
62 / 2 = 31 chromosomes
300
This is the one step that is identical in every way between meiosis and mitosis (description of step)
What is the first step where the DNA replicates (duplicates itself)
300
The step right before the main event in mitosis. (be specific about the chromosome's location)
They are lined up single-file in the middle of the cell
300
It is being produced in meiosis? A. haploid gametes B. haploid somatic cells C. diploid gametes D. Diploid somatic cells
What is A. haploid gametes
300
One comes from your dad's gamete and one comes from your mom's gamete. They are...
What are homologous chromosomes
300
This is a display of all your chromosomes sorted by size and chromosome name
a karyotype
400
During meiosis, homologous chromosomes exchange a little bit of genetic material. What do we call this exchange?
Crossing over
400
If a human cell has 46 chromosomes. How many chromosomes are in the cell during the main event?
2 x 46 = 92 chromosomes
...as they are held together as super chromosomes and lined up before the main event
400
They are identical and they make up a super chromosome.
What are sister chromatids?
400
Two chromosomes that are the same size, carry the same exact genes, and look the same under the microscope and are attached at the centromere.
(FYI the dot in the middle of the chromosome is called a centromere)
What are sister chromatids (or a super chromosome)
They are identical to each other
400
sister chromotids seperate in this main event...
What is Meiosis 2
the second splitting of the daughter cells into 4 gametes
500
What does the CELL looks like in the step when crossing over happens. Describe how many cells there are, (is it meiosis 1 or meiosis 2) and how the chromosomes look.
Meiosis 1 (there is 1 cell)
the super chromosomes are lining up in pairs in the middle in a line down the middle of the cell.
500
number of cells produced by mitosis
2
500
A ______ has the total amount of chromosomes for the organism. 1. Haploid 2. Diploid
What is 2. Diploid?
500
Long pieces of DNA that contains coding and non-coding sections.
What are chromosomes
500
After this point in meiosis there are no homologous pairs. What was our name for that point....
What is the main event of meiosis 1
(aka anaphase 1)
