evolution of
population!
100
how sexual selection may conflict with natural selection.
What is it does not take into account fitness.
100
shuffles the alleles in the gene pool. There are countless different combinations of genes that can be recombined into many different variations. This helps a population making all individuals a little be different because then if there is a problem such as a disease. There is a better chance that the disease will only affect a small portion of the population. This alters everyone's phenotypes.
What is Sexual recombination
100
A system of genes in which two alleles are maintained in stable equilibrium because the heterozygote is more fit than either of the homozygotes.
What is balanced polymorphism
100
Identify how natural selection causes evolutionary change through differential reproductive success.
What is Adaptation is gradual as natural selection increases alleles that are favorable.
100
is natural selection for mating success
What is sexual selection
200
marked differences between the sexes in secondary sexual characteristics
What is sexual dimorphism
200
Identify how genetic variation is preserved through diploidy
What is preserves genetic variation because instead of giving you the same exact 46 chromosomes as one of your parents you get 23 from each making up an entire set for a new living creature. By doing so you have less of a chance of receiving the same exact genes your parents did.
300
Identify how nonrandom mating can cause an increase in homozygosity but does not change gene frequencies.
What is Nonrandom mating - select mates for traits that are easily observable
