Punnett Square
Mitosis
True or False
Know the concepts
100
Instructions within DNA that cause a particular characteristic to be passed on from parent to offspring are called:
Genes
100
The mathematical chance that something will happen.
Probability
100
Correctly spell the final stage in Mitosis.
Cytokinesis
100
Alleles can have alternative versions. (Do not have to be the same)
False- Alleles can't have alternative versions. (They have to be the same)
100
is a diagram that is used to predict the genotypes of a particular cross or breeding experiment.
Punnett Square
200
The passing of genetic traits from parent to offspring is known as:
Heredity
200
What is Homozygous Dominant?
WW
200
In this step, the nuclear membrane dissolves, and the chromosomes condense into rodlike structures.
Prophase (mitosis 1)
200
There are 4 stages in Meiosis
False, there are 8
200
Explain the two-letter difference between Homozygous Dominant and Homozygous Recessive.
Dominant is both capital letters and Recessive has both lower case letters
300
A genetically produced characteristic, such as seed color, flower position , plant height, or seed texture.
Trait
300
What is Homozygous Recessive?
hh
300
Which of the six steps is Telophase?
It is the final stage in both meiosis and mitosis in a eukaryotic cell. (step #5)
300
Punnett squares predict only some of the possible outcomes of a genetic cross between 2 parents.
False- Punnett squares predict ALL the possible outcomes.
300
The amount of different cells do you have at the end of Meiosis
4 generally different cells
400
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell.
Meiosis
400
What is heterozygous?
Hh
400
When do chromosomes line up in a single file?
Metaphase (mitosis 2)
400
The Alleles Pp and pP have an identical phenotype.
True
400
A phenotype that shows a combination of both the original traits is a result of?
Incomplete Dominance
500
A diagram that shows the occurrence of a genetic trait in several generations of a family.
Pedigree
500
Crossing pea plants HH (Tall) with hh (Short)
in the first generation, how many of the four new plants will be short?
Zero
500
What happens in Anaphase?
The chromatids split apart and move to opposite sides of the cell.
500
An allele is an alternate form of a gene that governs an identifiable characteristic, like eye color or hair color.
True
500
What is the basic difference between Mitosis & Meiosis?
In both, the DNA replicates once.
In Mitosis the cell divides once.
In Meiosis the cell divides TWICE.
