The greatest amount of genetic variation occurs in offspring that reproduce —
sexually through fission
sexually through meiosis
asexually through mitosis
asexually through budding
The steps of crossing over during meiosis are shown in the diagram. What is the significance of crossing over in Meiosis I?
Crossing over ensures that the four daughter cells produced at the end of Meiosis II have the original number of chromosomes in each cell.
Crossing over ensures that the two daughter cells produced at the end of Meiosis I have half the original number of chromosomes in each cell.
Crossing over ensures that the same combination of alleles remains in each of the four daughter cells at the end of Meiosis II.
Crossing over ensures that the chromosomes in the four daughter cells produced at the end of Meiosis II will have a different assortment of genes than the corresponding chromosomes in the original cell.
There are a total of _______ chromosomes in human sperm or egg cells.
2
23
46
92
The cell division of meiosis occurs in how many sets of stages?
1
2
3
4
What happens before meiosis begins?
DNA is replicated in the original cell
Mitosis must be completed
Chromosomes line up at the equator of the cell
Homologous chromosomes separate
Homologous chromosomes contain the same genes.
True
False
During which phase of meiosis does crossing-over occur?
Prophase 1
Prophase 2
Metaphase 1
Metaphase 2
There are usually 46 chromosomes in a human ____ cell.
sperm
egg
haploid
diploid
What is the end result of meiosis?
2 identical daughter cells
4 identical daughter cells
4 haploid gamete cells
4 diploid gamete cells
What is the result of spermatogenesis?
4 haploid cells
4 diploid cells
2 haploid cells
2 polar bodies
How does mitosis differ from meiosis?
Mitosis makes gametes, while meiosis makes offspring cells
Meiosis makes haploid cells, mitosis makes diploid cells
Mitosis requires cytokinesis, meiosis does not
Mitosis makes gametes and meiosis makes zygotes
This law describes how each homologous pair separates independently of any other pairs during Anaphase I of meiosis
Law of Segregation
Law of Independent Assortment
Law of Gravity
Law of Mathematical Order
Meiosis is important for future generations
So the offspring has genes from both parents
So the offspring has genes from one parent
So the offspring has genes from neither parents
So the offspring makes its own genes
An extra chromosome on chromosome 17 is known as
Monosomy 17
Sex linked chromosomal disorder
Trisomy 17
Autosomal Chromosomal Disorder
An uneven division of chromosomes is known as
disjunction
non-disjunction
cancer
mitosis
Seperating Homologous pairs and creating genetic diversity is the goal of
Meiosis I
Meiosis II
Mitosis I
Mitosis II
