  1. When a population is reduced to a very small number of breeding individuals, random genetic changes called        occur.  As a result of these kinds of changes,
  • variation in genotypes and phenotypes will probably increase compared with the amount of variation present in the original population  TRUE  OR  FALSE?  
  • genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced populations  TRUE  OR  FALSE?
  • the reduced population will have a higher probability of extinction than a similar but larger population  TRUE  OR  FALSE?

Answer #1

Genetic drift

False: genotype and phenotype variation is a function of population size and smaller population results is less variation.

True

True.

  • Climate change is a threat to the existence of many species.

    QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

    In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...

    17.You are a geneticist studying the population genetics of Monarch butterflies. You are particularly interested in one gene for which the species has two alleles: B and b. Upon examining the alleles present in 100 individuals, you find that the B allele is very common, with an allele frequency of .6. Therefore, you calculate that there are a total of _______ b alleles present in the population. Group of answer choices A) 60 B) 80 C) 100 D) 120 E)...

    In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...
