What kind of cells does Mitosis occur in?
Somatic Cells
100
What type of cells do Meiosis make?
Gamete cells
100
Does DNA replication occur before Meiosis 2?
HECK NO! We would have trillions of chromosomes by now if it did
100
Crossing a Homozygous recessive with a heterzygous, what are the genotypes and phenotypes? Dominant allele is Awesomeness
50% Aa, 50% aa (sucks to be the aa)
100
Whats the SI's name? (hehehehe sorry I had to)
Nizar -__-
200
What are the four (or five) steps of Mitosis?
Prophase, Metaphase, Anaphase, Telophase, Cytokinisis
200
What are the replicated chromosomes called?
Homologs
200
Crossing over has already occurred between the homologs in Meiosis 1, does crossing over occur again between chromosomes in Meiosis 2? Why?
Yes, and this is due to the creation of such diversity.
200
What is it called when two alleles are phenotypically observable?
Codominance
200
What islands were important to Darwins study of evolution?
Galapagos
300
What is the line in which the chromosomes line up in called?
Metaphase plate
300
What causes diversity?
Crossing over, Random distribution.
300
Starting off with a diploid cell before Meiosis 1, how many cells do we have after Meiosis 2 and what type?
4 Haploid
300
What is it called when neither allele is observable and a new combination is observable?
Incomplete Dominance
300
What are the 4 ways evolution can occur? (If you have a good explanation of all, the points are doubles)
Mutation, Genetic Drift, Migration, Natural selection
400
What are the poles that pull the chromosomes apart called?
Centriols
400
What causes Down syndrome?
Nondisjunction
400
During the egg gamete replication what do we call the body that does not survive? and why does it not survive?
Polar Body, and that is do to the unequal distribution of the cytoplasm at cytokineses?
400
A homeless man who has A blood marries a movie star who has B blood. Their ugly child has O blood. What were the genotypes of the parents.
Ao and Bo
400
What causes mutation?
Spontaneous Mistake
500
Mitosis is similar to which Meiosis?
Meiosis 2
500
What is the outcome of Meiosis 1? (Specific name)
Two Diploid Cells
500
If the first diploid cell started off with 86 chromosomes, how many chromosomes does each haploid cell have?
43
500
Why is it that a most redheads have freckles?
two alleles on the chromosome are so close together that it is almost impossible to divide them during crossing over.
500
What is fixation?
the dying out of a certain allele and the increase of the other allele
