Document Summary
Dna segments: phenotype = the product of inherited genotype and environmental influence d. i. Some phenotypic differences are determined by a single gene and can be classified on an either-or basis d. ii. Other phenotypic differences are determined by the influence of two or more genes and vary among a continuum within a population. How is variation inherited: letter of darwin to j. d. In response, darwin proposed the pangenesis hypothesis, in which hereditary substances called gemules or pangenes are shed by all parts of the organism and carried in the bloodstream: 1990 = rediscovery of mendel"s law of heredity c. i. The preservation of genetic variation: udny yule shouldn"t all populations be composed of dominant alleles over time? a. i. Gene pools and allele frequencies: a population = localized group of individuals capable of interbreeding and producing fertile offspring, gene pool = consists of all the alleles for all loci in a population.
