Evolution
what is natural selection
when a certain variety in a species is more likely to survive so it becomes the most common
what is behavioral adaption
something an animal does in response to a certain stimuli to better its chances of survival.
What is Point mutation
A single nucleotide base is changed inserted or deleted resulting in a change to the DNA or RNA of a species.
Random Fertilization
When the female and male gametes fuse randomly after reproduction.
What is Inheritance
The passed down traits from parent to child
what is convergent evolution
Distantly related organisms evolve similarly because of the similar environmental necessities
What is Physiological Adaptation
Adaptations on the internal or cellular level which increases their chances of survival
what is Insertion
adding one or more nucleotide to a DNA sequence
Gene Immigration
When a new species comes to an environment and causes the the allele frequencies to change
What is variation
The difference cells, species, groups, and ETC.
what is a microevolution
Microevolution is a small change in a species that appears over a short period of time.b
what is an adaptive trait
A trait that makes an animal more likely to survive, and have offspring
What is Nonsense Mutation
A mutation in a sequence of DNA that makes an early stop codon. making less functional or no existent protein production
What is Genotypic Variation
A difference in the number or the structure of the Chromosomes or a difference in the genes carried by chromsomes
A physical Trait of a species
what is parallel evolution
Convergent evolution is when non-related species acquire similar traits while evolving together in the same ecosystem
what is co-adaptation
when two or more species, genes or phenotypic traits undergo selective pressure which makes one thing change making the other species gene or Phenotype change in response.
What is Frameshift mutation
when indels of many nucleotides in a DNA sequence not divisible by three. this means that the Insertion or deletion of Nucleotides will create a different translation
what is recombination
the process when pieces of DNA are broken up and then reorganized to produce new alleles.
The eventual decrease in an animal with a non-adaptive trait and vice-versa.
what is divergent evolution
Divergent Evolution is the accumulation of tiny changes in a species, causing species to change so much that they are different species. (usually happens because of changing geographical location)
What is Structural Adapatation
A physical change in a species
What is Missense mutation
A mutation where one nucleotide change makes a codon that codes for a different amino acid
What is Phenotypic Variation
The variety of traits in a species
What is a genotype
The genetic make-up of an organism
