Science - Classification, Variation and Adaptation Flashcards
Chromosome
An entire chain of Dna, along with a group of stabilizing protein. Also, it is DNA rolled up into a coil.
[P] Correlation
If two sets of data show correlation, it means they are somehow related or connected
[N] Correlation
A relationship between two variables such that as the value of one variable increases, the other decreases.
Nucleiotides
Chemicals A,C,T,G in DNA.
Inherited Traits
- Natural eye colour
*Natural hair colour
*Blood type
*Inherited diseases
Dominant Gene
when it effectively overrules the other (recessive) allele
Recessive
the alleles of the trait-causing gene are the same, and both (recessive) alleles must be present to express the trait
Characteristic, feature, trait
A distinctive, feature, or property of an or population.
Variation
Difference between individuals of the same species. Caused either genetically or environmentally.
Continuos Variation
Gradual changes in a characteristic e.g height.
Discontinuous Variation
Big variations that can be put into seperate categories e.g eye colour
Inherited Variation
A distinguishing quality or characteristic acquired from one’s ancestors that can be passed on to offspring.
Environmental Variation
A distinguishing quality or characteristic acquired from a change in the environment and cannot be passed on to offspring.
DNA
[Deoxyribonucelic acid] The chemical information to make organisms.
Double Helix
The shape of DNA found in the nucleus of a cell.
