Genetics
an alternate form of a gene
What is an alllele?
replaces thymine during transcription
What is uracil?
A statistic that expresses the extent to which differences in genes can account for differences in a trait
What is heritability?
shows the relationship between all living things
What is phylogeny?
change in a species over time
What is evolution?
the expressed, physical characteristic of a trait
What is a phenotype?
pairs up with cytosine
What is guanine?
multiple genes make up one trait
What is a quantitative trait?
phylogenic tree that branches repeatedly to show the evolutionary sequence of a species
What is a cladogram?
process by which species who compete well to fit in a certain environment
What is natural selection?
the inherited trait
What is a genotype?
do not code for proteins; stay in nucleus
What are introns?
traits that are passed down from parent to offspring; is applied to the individual
What is inheritance?
large families of similar genes that make up a species
What are homeobox genes?
environmental factors or constraints that push species to change and adapt
What is selection pressure?
the site of a specific gene on a chromosome
What is a locus?
replication errors
What are mutations?
same genes but differences likely due to differences in the environment
What is explaining the differences of a trait BETWEEN groups?
similar traits between two species that share an ancestor
What is homology?
had the same thought as Darwin that all living organisms are related
Who is Alfred Wallace?
genes for different traits are inherited separately
What is Mendel's Law of Independent Assortment?
sequence of three nucleotides
What are codons?
same environment but differences likely due to differences in genes
What is explaining the differences of a trait WITHIN groups?
traits between species that are alike due to environmental factors
What is analogy?
adaptation reflect and stem from our ancestors
What is the Environment of Evolutionary Adaptation (EEA)?
