Genetics Vocab Study Guide

making copies of organisms, each of which is a clone that receives DNA from only one parent cell

• genetics
• allele
• cloning
• recessive

inherited trait that makes an individual different from other species and results from a mutation in the organism's genes.

• variations
• trait
• gene
• genotype

an alternate form that a gene may have for a single trait; can be dominant or recessive

• genetics
• allele
• dominant
• Punnett Square

production of several species from one ancestral species.

• evolution
• natural selection
• adaptive radiation
• extinction

describes a trait that covers over, or dominates, another form of that trait.

• recessive
• cloning

• dominant

Change in the genetics of a species over time.

• evolution
• natural selection
• mutation
• extinction

occurs when the last member of a species dies; causes a loss of diversity among living things
