The stronger and usually more common allele.
What is Dominant?
When humans determine which organisms breed; the opposite of natural selection.
What is artificial selection?
This tool provides us with a prediction of all possible genotypes of offspring, given the genotypes of two parent organisms.
What is a Punnett Square?
DNA has a "backbone" made up of these 2 alternating substances.
DNA and RNA have slightly different jobs and RNA has this unique nucleotide base.
What is Uracil?
The weaker and usually less common allele.
What is recessive?
When humans breed the best-of-the-best (EX: to grow taller corn, sweeter grapes, etc.).
What is selective breeding?
If parent #1 has a genotype of Qq and parent #2 has a genotype of qq, this is the percentage we can predict to have offspring with the qq genotype?
What is 50%?
In DNA, Adenine pairs with this.
What is Thymine?
This is an organism's genetic code inside each of its cells.
What is genotype?
A unique version of a trait (gene).
What is an allele?
When humans alter the genetic structure of an organism through breeding (EX: A mule).
What is genetic engineering?
If B is brown hair and b is red hair, this is the percent of offspring we would predict to have red hair from a homozygous dominant dad and a heterozygous mom.
What is zero percent?
In DNA, Cytosine pairs with this.
What is Guanine?
This is an organism's physical appearance that depends on its genetic code.
What is phenotype?
The genotype when two different alleles are inherited.
What is heterozygous?
Creating a genetic copy of an organism (EX: Dolly the sheep).
What is cloning?
True or false? Punnett squares allow us to trace the presence of a trait (such as a disease) through multiple generations of people.
What is false? PEDIGREES allow us to do this.
The structure of DNA is often described with these 2 words.
What is double-helix?
This type of dominance will result in a blended phenotype if the organism inherits one of each unique allele.
What is incomplete dominance?
The genotype when two of the same alleles are inherited.
What is homozygous?
This person is known as the "Father of Genetics" and studied this plant.
Who is Gregor Mendel?
What is a pea plant?
I complete a Punnett square and see that 4 out of 4 boxes show me Rr. I can now make this prediction.
What is 100% will express the dominant allele?
What is 0% will express the recessive allele?
These 3 scientists (last names only) contributed greatly to our modern knowledge of DNA.
Who are Watson, Crick, and Franklin?
This type of dominance will result in a phenotype that shows BOTH alleles distinctly if the organism inherits one of each unique allele.
What is codominance?
