mendels first law correct answers When any individual produces gametes, alleles separate so that
each gamete receives only one allele for each gene
mendels second law correct answers all of the alleles of different genes assort independently of
one another during gamete formation
Meioses 1 correct answers alleles segregate in...
Meioses 2 correct answers duplicate alleles separate in...
gene pool correct answers sum of all copies of all alleles at all loci found in a population
mutations correct answers add new alleles to gene pool
populations correct answers individuals DO NOT evolve, blank do
adaption correct answers a favored trait that evolves through natural selection
gene flow correct answers migration of individuals and movement of gametes;
allele frequencies in a population correct answers gene flow changes
phenotype correct answers agents of evolution act on the
genetic drift correct answers caused by chance events that alter allele frequency in a population
, population bottleneck correct answers environmental conditions where only small # of
individuals survive due to random chance, large decrease in genetic variation
founder effect correct answers when individuals colonize a new region the small size of
populations reduces its genetic variation
sexual selection correct answers individuals of one sex mate preferentially with particular
individuals of the opposite sex
intrasexual correct answers improves the ability to compete for access to mates
intersexual correct answers makes them more attractive to opposite sex, peacock
non-random mating correct answers change in genotypic frequency NOT allele frequency
polymorphic correct answers a population with more than one allele at a certain locus
monomorphic correct answers one allele at a given locus, the allele is fixed
Allele freq correct answers measures the amount of genetic variation in a pop
genotype freq correct answers shows how a pop genetic variation is distributed among its
members
stabilizing selection correct answers preserves the average characteristics of a population by
favoring average individuals.
directional selection correct answers changes the characteristics of a population by favoring
individuals that vary in one direction from the mean of the population.
