Chromosome Flashcards
Chromosome
A single strand of DNA
Gene
A location on a chromosome that affects a trait
Allele
Variety of a gene
Genotype
The heritable component of a trait (AA
Phenotype
The measurable trait
Heterogeneous
A genotype with different alleles
Homozygous
A genotype with some alleles
Hemizygous
A genotype with partial/one alleles
Recessive
An allele that masked that is masked by another allele
Co dominant
Two different versions of the same gene are present
Dominant
An allele that masks the effect of other alleles
Genome
All the genetic info
Evelution
A change in frequencies over time
Altruism
Behavior that benefits the reciprecant but hurts the giver
Secondary sexual characteristics
Things people can see (Length of hair and how deep voice is)
Epistasis
Multi-genes = combine to make a phenotype
Pleiotrophy
One gene affecting
Genetic drift
Random events in a population that cause evolution
- more powerful in small population
Finders effect
The large effect on a population evolution trajectory because of specific founders
Natural selection
The differential reproductive success of an individual based on inheritable traits favored by the environment
Artificial selection
The differential reproductive success of an individual based on inheritable traits favored by humans
Sexual selection
The differential reproductive success of an individual based on inheritable traits favored by the mates
