How do you write a blood type O in a Punnett square?
The O blood type is a dominate allele and for the punnett square it will be written as “oo”.
The O blood type is a recessive allele and for the punnett square it will be written as “oo”.
The O blood type is a recessive allele and for the punnett square it will be written as “OO”.

A disease in which cells divide uncontrollably and destroy body tissue is called
Mitosis
Meiosis
Cancer
Hemophilia
Cancerous cells spend less time in mitosis than noncancerous cells
True
False
In Meiosis, crossing over occurs during
Prophase
Prophase 1
Anaphase
Anaphase 1
Crossing over is important because it
Increases genetic diversity
Decreases Genetic diversity
Produces identical cells
Prevents mutations
Which step in protein synthesis occurs directly after mRNA is assembled
A portion of mRNA is used to form energy
A section of DNA is removed by the mRNA
mRNA is transported out of the nucleus
mRNA is attached between 2 strands of DNA
Farmers must plant a variety of crops to increase
Diseases
Genetic diversity
Toxicity levels
Genetic homogenous crops
Tumor- suppressor genes prevent cells with damaged DNA from undergoing mitosis. What would happen is a mutation stopped this function?
Tumor cells would continue to divide
Tumor cells would attack healthy cells
Cells would produce more protein
Meiosis would stop
Which cells perform mitosis?
Gametes
Sex cells
Sperm and egg
Somatic cells
Mitosis results in
Identical cells
Genetically diverse cells
4 identical cells
Haploid cells
What happens in mitosis to main chromosome number
Chromosomes cross over
Duplicated chromosomes are split into 2 identical cells
Genetic information is shared
Independent assortment
Sex linkage applies to genes that are located on the sex chromosomes. Why are they considered sex- linked?
They are more common in females
They are gametes
their expression and inheritance patterns are the same in males and females.
their expression and inheritance patterns differ between males and females.
Macromolecules are made of smaller units called
Disaccharides
Monomers

adenine, guanine, cytosine, and thymine
adenine, guanine, cytosine, and thorzine
There are only 3 bases
Each section of DNA strand has a base sequence of GCATAC, which base sequence is the complementary DNA for GCATAC?
CATACG
CGTATG
GCATAC

The process by which DNA is copied to RNA is called
Transcription
Translation
Codominance
Incomplete dominance
Process by which RNA is used to produce proteins is called
Transcription
Translation
Polygenic
Segregation
Mendel's law of independent assortment states that
only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random
the alleles of two (or more) different genes get sorted into gametes independently of one another.
The genetic code is universal, unambiguous, and redundant
Scientific laws can change
The Law of Segregation states that
The genetic code is universal, unambiguous, and redundant
the allele a gamete receives for one gene does not influence the allele received for another gene
the alleles of two (or more) different genes get sorted into gametes independently of one another.
only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random.
Codominance is
a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual
a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in a different phenotype
an interaction between alleles from a polygenic trait (a trait that involves multiple genes) where one allele dominates the other alleles.
the alternative forms of the same gene so they influence the same trait.
Polygenic
trait is a characteristic, such as height or skin color, that is influenced by two or more genes
Phenotyic
trait is a characteristic, such as height or skin color, that is influenced by one gene
The presence of two identical alleles at a particular gene locus.
Incomplete dominance is
a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.
a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in a different phenotype
traits that are influenced by genes carried on the sex chromosomes
Phenotypic
