PT 854 THERMAL STRESS FEVER AND INFECTIOUS DISEASES EXAM WITH COMPLETE
SOLUTIONS 100% VERIFIED LATEST UPDATE!!
parsimony principle - (ANSWER)accept the simplest explanation that agrees with the known facts
concentric circles - (ANSWER)# spike protein mutationos compared to original
viral "strain" - (ANSWER)variant that's different (or relevant) "enough" to call special attention to
SNP ("snip") - (ANSWER)single-nucleotide polymorphism
SNP map - (ANSWER)locations of SNPs on chromosomes
recombination - (ANSWER)genetic shuffling when eggs & sperm are produced
T/F: there are multiple ways to draw the same tree - (ANSWER)True (etc., horizontal, vertical, circle,
semi-circle)
T/F: As the pandemic spread, each of these strains (original, alpha, gamma, delta, omicron, etc.) did
evolve from the one it replaced - (ANSWER)False
T/F: Two is the maximum number of alleles that can exist at a time at a locus. One must become fixed
before a new one can arise. - (ANSWER)Flase --> many loci, always mutating --> many loci on a
chromosome
T/F: After a sufficiently long time, the fraction (%) of neutral sites on the DNA that are polymorphic will
stabalize - (ANSWER)True --> mutation giveth & drift taketh away
Natural selection within a population tends to ______ genetic variation - (ANSWER)reduce
Genetic drift within a population tends to ______ genetic variation - (ANSWER)reduce
