Mendelian Genetics
The different types of genes. You receive one from your mother and one from your father.
What are alleles?
More than one gene controls the expression of a trait.
What is polygenic or polygenetic inheritance?
These special enzymes cut up DNA into different sized fragments.
What are restriction enzymes?
The process by which organisms maintain a stable internal environment.
What is homeostasis?
Small changes over a short period of time.
What is microevolution?
The expression of genes in traits.
What is phenotype?
The heterozygous form is a "mixture" of the dominant and recessive traits.
What is incomplete dominance?
New technology which is very precise in cutting and inserting genes.
What is CRISPER?
The type of intramolecular bonds which give water its surface tension and high boiling point.
What are hydrogen bonds?
Small changes over a long period of time which may eventually result in a new species.
What is macroevolution?
The plants that Mendel used for his studies.
What are pea plants?
More than two alleles determine the expression of a trait.
What is multiple alleles inheritance?
Technology which allows us to separate DNA based on size using electricity.
What is gel electrophoresis?
The building blocks of life. The simplest form of organization in all life.
What are cells?
A random change in the sequence of DNA.
What is a mutation?
The protein that chromatin wraps around to form the chromosomes. Hint (it starts with an H)
What are histones?
The dominant alleles are both expressed in this type of inheiritance.
What is co-dominance?
DNA technology which creates an exact genetic copy of an organism.
What is cloning?
Percentage of a heterozygous organism when a tall pea plant TT is crossed with a short pea plant tt.
What is 100%?
This type of species would be the "in between" in the formation of one species from another.
What are intermediate (or transitional) species?
The process by which chromosomes exchange material during prophase 1.
What is crossing over?
Blood types A, B, AB, and O show both of these types of inheritance.
What are multiple alleles and co-dominance?
DNA technology which allows identification of felons based on DNA left behind at crime scenes.
What is DNA fingerprinting?
The process by which some organisms emit light as a form of mating attraction, attraction of prey, or evasion of predation.
What is bioluminescence?
A process of microevolution where organisms survive to pass on their genes because of an advantage.
What is natural selection?
