BIOL 1001 : Exam 4 Class Notes
Document Summary
Work was rediscovered after darwin: by the late nineteenth century, natural selection suggested that a population could evolve if members show variation in heritable traits. Variations that improved survival chances would be more common in each generation in time, the population would change or evolve. The theory of natural selection did not fit with the prevailing view of inheritance blending: blending would produce uniform populations; such populations could not evolve. Each trait is determined by a pair of genes: 2. Law of segregation= pairs of genes are separated during gamete formation: 3. Random chance determines which gene goes to which gamete: 4. They may be more than one form of a gene (alleles: dominant will always mask recessive, 5. For a given trait (gene): heterozygous= pair of alleles are different, homozygous= pair of alleles that are the same, genes, alleles, and chromosomes, locus= position of gene on chromosome, genetic symbolism, 1.
