Biology Mitosis
1. daughter cells are diploid 2. daughter cells are haploid 3. produces 4 daughter cells 4. daughter cells are identical 5. produces 2 daughter cells 6. takes place in all cells 7. only takes place during gamete formation 8. creates a recombination of genes for better diversity

A diploid cell enters meiosis with 20 chromosomes. How many chromosomes will each daughter cell have?
10
A diploid number is 100 for a particular organism , if this organisms cell undergoes mitosis each daughter cell will contain ____ chromosomes. 50 25 100 200
100
The diploid number for a particular organism is 200 what is it's haploid number? 100 400 150 200
100
If an organisms haploid number is 6, it's diploid number is
12
A diploid cell enters meiosis with 10000 chromosomes , how many cell divisions will it go through?
2
If the diploid number of chromosomes for an organisms is 40,each daughter cell after mitosis will contain _______ chromosomes.
20
A chimpanzee has 48 chromosomes in all of it's cells, there for the chromosome number of a chimpanzee is
24
If a diploid's number is 48 what is it's haploid numbers?
24
The Giant Earthworm of Africa has a diploid number of 36, therefore its gametes will have how many chromosomes ?
36
A diploid cell enters meiosis with 16 chromosomes , how many daughter cells will it produce?
4
The difference in mitosis and meiosis is that in meiosis there are____daughter cells which are______________ 2 and haploid 4 and diploid 2 and diploid 4 and haploid
4 and hapliod
What is formed at the end of meiosis
4 genetically different cells
Unlike mitosis, meiosis results in the formation of
4 haploid cells
If an organisms haploid number is 23, its diploid number would be
46
A diploid cell enters meiosis with 16 chromosomes , how many chromosomes will each daughter cell have?
8
Where are genes located?
On chromosomes
Gametes have: which are correct Twice the number of chromosomes found in body cells One allele for each gene Two sets of chromosomes Homologous chromosomes Haploid number of chromosomes Diploid number of chromosomes
One allele for each gene and Haploid number of chromosomes
What is the result of the process of crossing over?
Recombination of genes
The gametes of sexually reproducing organisms are haploid
The statement is true
A gamete must contain one complete set of genes
This is a true statement
The offspring of two parents obtain a single copy of every gene from each parent
This is a true statement
Genes are located on specific positions on spindles
This is a true statement if you changed spindles to chromosomes
Haploid numbers are always_____________ where as diploid numbers are always _________________ Even Odd both
both even
Genes are located at specific positions on_______________
chromosomes
Genes are located on specific spots on where? Endoplasmic reticulum Nucleolus Mitochondria chromosomes
chromosomes
During tetrad formation, alleles can be exchanged between chromatids, this is known as tetrad formation zygote formation crossing over diploid cell formation
crossing over
During the formation of tetrads in prophase one, alleles are exchanged between chromatids , this process is:
crossing over
During the formation of tetrads in prophase one, alleles are exchanged between chromatids, this process is: Fertilization Diploid formation Crossing over Tetrad formation
crossing over
The chromosomes in this illustration are showing
crossing over in meiosis
Which describes the cells at the end of Meiosis II and the original cell Daughter cells have one copy of all the genetic material daughter cells have one copy of half of the genetic material daughter cells have two copies of all the genetic material daughter cells have two copies of half the genetic material
daughter cells have one copy of half of the genetic material
Haploid number of chromosomes may be even or odd, a diploid number is always
even
While a haploid number of chromosomes may be even or odd, a diploid number is always
even
Specific spots on chromosomes Are;
genes
Gametes have _____ number of chromosomes diploid haploid homozygous heterozygous
hapliod
N cells are
haploid
Chromosomes that are pairs that correspond to each of the parents body cells are
homologous
Gametes are produced by the process of
meiosis
Gametes are produced by this process Meiosis Mitosis Independent assortment Incomplete dominance
meiosis
Which process produces gametes mitosis binary fission spore production meiosis budding
meiosis
The process which produces two identical diploid cells? Meiosis Mitosis
mitosis
Which process produces 2 genetically identical daughter cells? meiosis mitosis spermatogenesis oogenesis pollination
mitosis
Gametes have
one allele for each gene
Unlike mitosis, meiosis in male reptiles results in the formation of:
one haploid cell 4 haploid gametes
In Meiosis 1 The end results are 2 identical cells (reduction) In Meiosis II, there are 4 haploid cells non are identical
remember
Four chromatids in meiosis are cross overs tetrads triads zygote
tetrads
A cell that contains both sets of homologous chromosomes are haploid
the statement is true if you changed haploid to diploid
One member of each homologous chromosome pair comes from each gene
the statement would be true if you changed gene to parent
After the egg is fertilized it becomes a __________ which then undergoes cell division by mitosis and eventually becomes a complete organism
zygote
After the egg is fertilized, it becomes a
zygote
The body formed by the union of egg and sperm gamete tetrad zygote
zygote
Chromosomes that are pairs that correspond to each of the parents body cells Tetrads Haploid Homologous Homozygous phenotype
Homologous chromosomes
