Biology - MCAT Flashcards
What pancreatic cells cause exocrine secretion of digestive enzymes?
acinar
ABO blood types are an example of what kind of dominance?
codominance
The likelihood (percentage) that you will express a phenotype given you have the genotype is known as what?
penetrance
The degree to which you express a trait is known as what?
expressivity
Will genes that are closer together or farther apart be more likely to undergo recombination?
farther apart
What type of mutation is never found in germ cells and therefore cannot be passed to offspring?
somatic mutation
The equation p+q=1 accounts for genotype or allele frequency?
allele frequency
What type of selection promotes the survival of the group?
inclusive fitness
The ability to reproduce many off spring is known as what?
fitness
If an overweight male has a kid with a thin female, the kid will probably have average weight and this is known as what?
stabilizing selection
If there’s many birds with large and small beaks but not many with medium, that’s known as what?
disruptive selection
If a disease breaks out and kills most of the population but a small random group lives, what is this known as?
bottleneck effect
What is it called when there is a movement of alleles due to migration between populations?
gene flow
What type of symbiosis allows one species to benefit and the others to not be harmed but also not benefit?
commensalism
What type of anaerobes don’t need oxygen but will use it when present?
faculatative anaerobes
