What is the difference between meiosis and mitosis
Mitosis is for body cells and meiosis is for sex cells
They are spelled differently
Mitosis is for sex cells and meiosis is for body cells
True or false: Asexual reproduction requires one parent
True
False
In which phase of meiosis do the chromosomes cross over?
Metaphase 2
Anaphase 1
Cytokinesis
Prophase 1
In which phase of meiosis do the homologous line up along the equator?
Prophase 2
Anaphase 2
Metaphase 1
Telephase 2
In which type of division do the cells divide twice?
Meiosis
Mitosis
What phase of the cell cycle is the longest?
Telophase
Anaphase
Cytokinesis
Interphase
Where are the cell chromosomes stored?
In the ribosomes
In the lungs
In the nucleus
In the mitochondria
How many chromosomes are in a somatic cell?
3
23
490
46
How many chromosomes are in a gamete?
99
70
23
46
Why are gametes (sex cells) considered haploids?
because they have only one pair of chromosomes
because they have two pairs of chromosomes
because they have one more chromosome than other cells
because they have no chromosomes
What happens during anaphase 1?
crossing over occurs
the chromatids separate
the spindle fibers move the chromosomes to opposite sides
chromosomes line up along the equator
In what phase do the cells actually separate?
telophase 1
anaphase 2
cytokinesis
telophase 2
In which phase does the cytoplasm divide and 2 daughter cells form
Telophase 1
Telophase 2
Why is crossing over important?
because it allows for genetic variation
because it takes time
because it causes identical offspring
because it helps the offspring become prettier
What type of cell division results in identical offspring?
Mitosis
Meiosis
Mitosis (select all)
One parent
Genetic variation
Identical offspring
No need for mating
Two parents
Meiosis (select all)
One parent
Genetic variation
Identical offspring
No need for mating
Two parents
In which phase do the chromatids separate?
Anaphase 1
Telophase 2
Prophase 2
Anaphase 2
What happens during interphase?
cells divide
chromosomes are duplicating
chromosomes are deteriorating
chromosomes are crossing over
What is the monomer of nucleic acid?
monosaccharides
nucleotides
glycerol
amino acids
