Process by which organisms with favorable traits survive and reproduce

• Natural Selection

• Fossil Record

• Diversity

• Evolution

A particular trait that helps an organism survive in its environment

• Molecular Homology

• Advantage

• Adaptation

• Evolution

form of a gene that controls a characteristic

• allele

• trait

• sex chromosome

• recessive trait

inherited combination of alleles that is represented by two letters

• Phenotype

• Homozygous

• Genotype

• Punnett Square

Homozygous means

• inheritance patterns that express incomplete dominance

• occurs when two copies of the allele are the same

• an organism’s specific characteristic

• occurs when two copies of the allele are different

trait that is expressed over a recessive trait

• Dominant Trait

• Sex Chromosome

• Recessive Trait

• Heterozygous

Phenotype is

• an organism’s specific characteristic

• structure in a cell’s nucleus that contains DNA

• occurs when two copies of the allele are different

• organism’s expressed appearance based on its genotype

Natural Selection

• process by which organisms with a certain set of favorable traits survive

  and reproduce other individuals with the same set of traits

• the differences seen between individuals of the same species and

  between species themselves

• theory that all organisms descended from a mutual species

a particular trait that helps an organism survive in its environment is ...

structural similarities between different species like the bones in bird’s wing being similar to the bones in a human’s arm
