Campbell Biology, Chapter 23 Flashcards
Does evolution occur in populations or individuals
Populations, occurs as natural selection occurs.
What are the different types of Heritable Phenotypic differences
“Either-or” traits determined by a single gene locus or Continuous variation, which results from multiple genes influencing a trait
Variations in Exons do not do what
Alter amino acid sequences
Phenotype = _____ + _______
Genotype + environmental influence
How do mutations form
Errors during DNA replication or Exposure to UV light, radiation, or chemicals
What are point mutations
Single-base changes that can significantly affect phenotype
What mutations are heritable
Mutations in gametes
What is Hardy-Weinberg equilibrium
the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
