Evolution, Sexual Selection, Allele, Negative Selection, Genetic Variance,…
Evolution
occurs due to
Sexual Selection
Mate choice
or
Intersexual selection
same sex compete for mating
Intrasexual selection
Allele
vary in the population
Genes
expression causes specific
Phenotype
is composed of
2 different alleles
Heterozygous
same allele
Homozygous
Negative Selection
variants dissappear
reselection applied against extreme values of a character
Stabilizing Selection
Genetic Variance
measured in terms of
Genotypic frequencies
Phenotypic frequencies
leads to
Allele frequency
due to changes in
Hardy Weinberg Equillibrium
disrupts
due to altered
Chromosome
occurs in
Mutanion
caused by the occurrence of
Positive selection
variant frequency increase
Natural selection
Balancing Selection
multiple alleles actively maintained
Disruptive Selection
2 extreme selected
Directional Selection
single extreme selected
