Mitosis cell division
Meiosis (True or False)
Genetic crosses
Genetic crosses(2)
Melosis
100
produces spindle fibers pull chromosomes apart
What is centriole
100
Prophase I - is where Chromose Duplication Doesn't Occur.
False
100
different forms of gene
What are alleles?
100
both copies of gene in offspring that are the same
What is homozygous?
100
same as prophase of mitosis but homologous chromosomes line up next to each other.
What happens in prophase 1?
200
prophase
What is the first mitosis stage
200
Metaphase I - is the Second Stage in Meiosis II.
False
200
genes that produce traits that are expressed..usually gene that is turned on
What are dominant genes?
200
used for determining the probabilities of outcomes of a cross.
What is ponheit squares?
200
chroomosome line up on metaphase plate with homologous chromosomes on each side.
What happens in metaphase 1?
300
before or early
What does prophase mean?
300
The end result of Meiosis I is the form of two haploid cells.
True
300
recessive gene
What are genes that cause the traits that are not expressed... usually the gene that is turned off.
300
ploidy number
What are the number of each copy of chromosome called?
300
chromosomes are pulled to poles, but the sister chromosome dont seperate.
What is what happens in anaphase 1?
400
opposite sides
where does centrioles move to?
400
physical characteristics that show up in a cross
What is phenotype
400
gametes
What are usually the only haploid cells in humans
400
meiosis 1 and mitosis 2
What are the two cell divisons
500
metaphase
what is the second stage of mitosis
500
zygote
What is a fertilized egg
500
genetic combination that shows up as a result of a hybrid cross.
What are genotypes?
500
23pairs and 46total...one for mother and one father
how many chromosomes does humman have? and how many for mother and father?
500
one goes into the cell..and the other goes into another cell.
What happens too the homologous pairs in anaphase 1?
