ASU BIO 345 Exam 1| Questions and answers 2023/24 | GRADED A+ D ≈ 0.49 A population of butterflies comes in three color morphs; orange (A1A1), black (A2A2), or orange with black spots (A1A2). You find that the frequency of orange butterflies is 0.49, and the frequency of black butterflies is 0.36. You do not know if the population is currently in HWE. What would you expect the frequency of spotted butterflies to be, if the population is under Hardy-Weinberg equilibrium? A ≈ 0.42 B ≈ ...

Test Bank, Chapter 3 1. Lord Kelvin argued that based on the temperature of rocks, the earth could not be as old some geologists thought. What turned out to be wrong with his reasoning? (a) he claimed that the temperature of surface rocks should be used in calcuations, but these calculations were shown to be unreliable (b) he did not realize that the planet’s interior was constantly changing (c) the upper layers of the earth are cooler than Kelvin realized (d) all of the above 2....

If there are two alleles at a single locus (A1 or A2) and the frequency of the A1 allele is 0.3. What would the frequency of the A1A1 genotype be at Hardy-Weinberg Equilibrium? A. 0.09 B. 0.30 C. 0.42 D. 0.70 E. 0.91 3. If the fitness of the BB genotype is 1.0, the fitness of the Bb genotype is 0.8 and the fitness of the bb genotype is 0.8, which of the following is true? A. B is dominant to b B. B is recessive to b C. The B allele will decrease in frequency D. Selection will never ...

change from gen to gen via selection of heritable traits evidence for evolution - Answer - fossils - extinction - transitional forms - vestigial traits why is the myth about evolution being goal oriented false? - Answer species do not adapt because they "want" or "need" traits; they adapt them because an ancestor with that triat just so happened to reproduce sooner or more successfully than others why is the myth that evolution is a hierachy false? - Answer evolution is more a ne...

Gene pool all of the alleles of all the genes in a certain population Hardy-weinberg principle genotype frequencies in a large population do not change from generation to generation in the absence of evolutionary processes Claims of hardy-weinberg principle (1) if the frequencies of alleles a1 and a2 in a population are given by p and q, then the frequencies of genotypes a1a1, a1a2, a2a2 will be given by p^2, 2pq, and q^2 for generation after generation. (2) when alleles are transmitted via me...
