Principles of Heredity
Who discovered the concept of genetic inheritance?
Gregor Mendel
Incomplete Dominance
Adaptation
Observable characteristics of an organism.
Character
Thymine
Phenotype
When traits from both parents are expressed simultaneously.
Codominance
Natural selection passes on what to their off spring?
Adaptations
Character having two or more forms.
Traits
During transcription, DNA is unzipped and then an enzyme produces what with nucleotides?
RNA
What allele phenotype is expressed in a hybrid organism?
Dominant Allele
When parents blend their traits in the offspring, this is called..
Incomplete Dominance
When a population randomly changes its traits over time.
Genetic Drift
Hybrid Crossing
What grabs the nucleotides to produce a new strand of DNA during replication?
Enzymes
If a RR or Rr cross, what is probability of the dominant trait being expressed?
100%
When a gene has more than two possible alleles.
Multiple Allele Inheritance
Who believes in natural selection that produces different species, but not whole new organisms?
Creationists
In a phenotype, both alleles are expressed.
Codominance
What are the four phases of mitosis in order?
Prophase, Metaphase, Anaphase, & Telophase
What do you call the dominant trait always being expressed in a hybrid organism?
When more than one gene is responsible for a phenotype, this is called...
Polygenic Inheritance
What does natural selection and genetic drift do over time to a population's genetic make up?
Decreases genetic information
Two or more genes from the same or different chromosome controlling a single character.
Polygenic Inheritance
What do tRNA have in order to read the mRNA nucleotides?
Anticodons
