He is an Austrian monk who discovered the basis of inheritance.
Who is Gregor Mendel?
100
These cells undergo division during Meiosis.
What is a Germ Cell?
100
G1 phase, S phase, and G2 phase all occur during this part of mitosis.
What is Interphase?
100
Someone with this disease lacks brown pigment.
What is Albinism?
100
The universal blood donor.
What is type O blood?
200
This type of inheritance can only occur when both parents are at least heterozygous for a particaular trait.
What is Autosomal Recessive?
200
A homologous pair formed during Prophase of Meiosis containing four chromatids.
What is a tetrad?
200
These are the two structures in a chromosome that are genetically identical which are held together by a centromere.
What are Sister Chromatids?
200
Muscular Dystrophy is this type of inheritance, as it commonly affects males.
What is X-Linked Recessive?
200
An organism with unknown genotypes is always crossed with this during a test cross.
What is a Purebred Recessive?
300
This is the blending of two traits.
What is Incomplete Dominance?
300
The process where non-sister chromatids exchange genes during Prophase I, allowing for the recombination of genes.
What is Crossing Over?
300
A process where sister chromatids align along the equator while spindle fibers attach to the centromere of the replicated chromosomes.
What is Metaphase?
300
Blood clotting, reduced blood flow, constant pain, and little energy is the result of this codominant disease.
What is Sickle Cell Anemia?
300
When individuals with contrasting traits are crossed, the offspring will express only the dominant trait.
What is the Principle of Dominance?
400
This occurs when one or more base pairs are added or deleted from a DNA strand, where all codons code for different amino acids.
What is a Frame Shift Mutation?
400
The random positioning of tetrads along the cell's equator.
What is Independent Assortment?
400
This process is the division of the cytoplasm to form two new daughter cells.
What is Cytokinesis?
400
A child with this disease would appear normal at birth, but their brains and spinal cords begin to deteriorate at about 8 months.
What is Tay-Sach's Disease?
400
He theorized that offspring had variations of their parents' characteristics, but he was unable to explain the basis of heredity.
Who is Charles Darwin?
500
This is the failure of chromosomes to seperate properly during Meiosis, resulting in the addition or deletion of one or more chromosomes from a gamete.
What is Nondisjunction?
500
This is the pairing of homologous chromosomes during Prophase I.
What is Synapsis?
500
This is made up of DNA and proteins that condense and thicken during Prophase to form visible duplicated chromosomes.
What is Chromatin?
500
This disease causes one to have only half the number of LDL receptors and two times the normal blood cholesterol level.
What is Familial Hypercholesterolemia (FH)?
500
This states that hereditary traits are determined by pairs of alleles from each parent. These alleles separate during gamete formation, giving each offspring only one allele from each parent.
