Who is the father of genetics?
Gregor Mendel
This is the likelihood that an event will occur, it is used to predict the outcome of genetic crosses.
probability
This is the name of the genetic makeup of an organism; it is represented by letters. And this the the name of the physical characteristic.
genotype; phenotype
A sequence of DNA that codes for a particular characteristic
What is a Gene?
A fixed position or location on a chromosome
What is a locus?
Mendel worked with these organisms to study the inheritance of traits
pea plants
This is the reason why short plants disappeared in Mendel's F1 generation of pea plants
All the F1 generation were heterozygous for plant height and since the tall trait is dominant it covers the recessive short trait.
Different forms of a gene are called this; Mendel called them factors.
Alelles
This vector can be used to carry a good genes into a human cell, but also can be risky.
What is a Virus?
molecule used to cut DNA
What is an enzyme?
Name the 4 phenotypes discussed in Mendels Peas
Round, Wrinkled, Green and Yellow
These are the offspring genotype when plants with the following alleles are crossed: TT and Tt
50% TT and 50% Tt
This is another name for a homozygous genotype.
purebred
Change that occurs in a DNA sequence
What is a mutation?
In most sexually reproducing organisms, each adult has this many copies of each gene.
2 copies, one from each parent.
Mendel discovered that this type of trait could only show if it paired with another trait that was the same type.
recessive
This is a diagram that illustrates all of the possible genetic combos that can occur during sexual reproduction
Punnett square
This is another name for a hybrid genotype.
heterozygous
a child whose genetic makeup has been selected or altered, often to include a particular gene or to remove genes associated with disease.
What is a designer baby?
Technique Mendel used to pollinate the flowers of his pea plants. He did this by cutting off the male parts of one flower and dusted the female part with pollen from another flower.
What is cross-pollination?
When an organism inherits two of the same alleles, we describe this genotype as being __________. And when an organism inherits two different alleles, we describe this genotype as being __________.
homozygous; heterozygous
This is the principle that states that genes for different traits can segregate independently during formation of gametes.
What is the Principle of Independent Assortment
a process in which he number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
What is Meiosis?
research investigations in which people volunteer to test new treatments, interventions or tests as a means to prevent, detect, treat or manage various diseases or medical conditions.
What is a clinical trial?
Name the chemical that was either bitter or tasteless to students in our paper tasting activity.
What is Phenylthiocarbamide (PTC)?
