Vocabulary
These are considered new organisms produced through reproduction
What is offspring?
A characteristic that is passed through genetic material
What is trait?
a version of a gene that only expresses its associated trait or phenotype when an individual inherits two copies of it—one from each parent.
What is recessive allele?
The genetic make up of an organism
What is genotype?
Selective breeding is used to pass on desirable _______ to offspring
What are traits?
This is a reproductive process that involves only one parent and produces offspring that are genetically identical to the parent
Daily Double
What is asexual reproduction?
process by which individuals that are better suited to their environment survive and reproduce more than other members of the same species
What is natural selection?
a variant form of a specific gene, representing different versions of a DNA sequence at a given genomic location
What is an allele?
One example of phenotype is...
Hair color, eye color
True or False: Genetic variation increases in artificial selection.
What is false?
to obtain genetic material from a parent
What is to inherit?
reproductive process that involves two parents combining their genetic material to produce offspring that differ from both parents
What is sexual reproduction?
the basic physical and functional unit of heredity, composed of specific sequences of DNA that provide instructions for making proteins or functional RNA molecules
Daily Double
What is a gene?
Physical traits of an organism
What is phenotype?
This phrase, often used for natural selection, describes how individuals better adapted to their environment survive.
What is survival of the fittest?
process by which humans breed only those organisms with desired traits
What is artificial selection?
a visual, grid-based diagram used by biologists to predict the potential genotypes and phenotypes of offspring from a specific cross or breeding event.
What is a punnett square?
He invented the punnett square
Who is Reginald C. Punnett?
Hair color, eye color and height are also considered these...
What are inherited traits?
These molecules, which carry genetic information, are modified over generations of breeding.
What is DNA?
group of organisms that make up a single step in the line of descent from an ancestor.
What is a generation?
a genetic variant that expresses itself more strongly
What is a dominant trait?
He studied the passing of traits from parent to offspring
Who is Gregor Mendel?
In artificial selection, this group decides which traits are favorable, rather than the environment.
Who are humans?
This term defines a trait that is beneficial for survival, often lost in artificial selection.
What is adaptation?
