Document Summary

Outcomes: understand why assessing genotype is difficult, know hardy-weinberg. Characteristics of each population will determine how/when a species will outstrip ability of community to support it. Fate of population depends on characteristics related to reproduction. Reproductive potential and reproductive effort greatly exceed requirements of reproductive replacement. Genotype: governs reproductive output and affects competitive ability, determining genotype is complicated because, phenotype may be similar for multiple genotypes, environmental effects may interfere with phenotypic expression, multiple alleles/genes may be implicated in a single phenotype. Study generations: genotype frequencies of adults, compare one generation to the next generation (the hard and complicated way), establish mating rule (random or assortative, frequencies of mating between genotypes, genotype frequencies of offspring, frequencies at birth. Hardy-weinberg: (cid:1868)2+(cid:884)(cid:1868)(cid:1869)+(cid:1869)2=(cid:883, (cid:1868)+(cid:1869)=(cid:883, makes predictions of what genotypes will be from known allele frequencies, p= frequency of dominant allele, q= frequency of recessive allele.
