Natural selection
Natural selection
Process where better-suited organisms survive & reproduce more
Advantageous alleles
Advantageous alleles
Gene versions that help organisms survive and reproduce
Selection pressure
Selection pressure
Environmental factor affecting organism's survival & reproduction
Copies needed for dominant allele to show trait
Copies needed for dominant allele to show trait
One copy
Copies needed for recessive allele to show trait
Copies needed for recessive allele to show trait
Two copies
Why dominant alleles spread faster than recessive
Why dominant alleles spread faster than recessive
Only need 1 copy to show trait vs 2 for recessive
Carrier (recessive trait)
Carrier (recessive trait)
Individual with 1 copy of recessive allele, doesn't show trait
Why use simulations for natural selection
Why use simulations for natural selection
Compress evolution from thousands of years into minutes
Effect of no selection pressures
Effect of no selection pressures
No evolutionary change occurs
