A segment of a DNA molecule.
What is a “gene”?
Type of allele that, if present, always displays that trait.
What is “dominant”?
Permanent change to a gene.
What is “mutation”?
Process by which individuals with traits that are best suited for their environment are more likely to survive.
What is “natural selection”?
Where genes are located.
What is along a “chromosome”?
Type of trait that needs both alleles to show up in offspring.
What is “recessive”?
An example of a healthy mutation.
What is “sickle-cell”?
Producing more offspring than can actually survive.
What is “overproduction”?
Determines the order of amino acids, which controls all life processes, like photosynthesis and building body structures.
What is “genetic material”?
Occurrence of differences in the same trait.
What is “variation”?
An unhealthy mutation.
What is “albinism”?
The struggle for existence in nature.
What is “competition”?
Number of chromosomes each reproducing parent gives offspring.
What is “27”?
The two factors that determine variation.
What are “genetics” and “environment”?
Environmental factors that can damage DNA.
What are “UV and chemicals”?
Necessary for natural selection and evolution to occur, or species would all be exactly the same.
What is “variation”?
Traits are guided by these different forms of genes.
What are “alleles”?
Variations that result from differences in genetic material.
What are “genetic variations”?
Two processes, in sexual reproduction, where DNA is copied.
What is “meiosis and fertilization”?
Types of temperatures that cause faster evolution.
What are “higher temperatures”?
