PACK 19: VARIATION AND POPULATION GENETICS Flashcards
(7 cards)
define variation
variation describes the differences in characterises or phone types that exist
define inter specific variation
variation between different species
define intra specific variation
variation within the same species
what are the causes of genetic variation
meiosis, mutations, and random fusion of gametes
how does meiosis introduce variation
through crossing over and independent segregation
how do gene mutations lead to the privation of non-functioning proteins?
the sequence of bases is altered, changing the sequence of amino acids coded for in the protein. this causes a change in the tertiary structure of the protein which can lead to a loss or reduction in the function of the protein
what are the types of
