As you return to the population you note that many (but not all) of the flowers have a faint purple vertical stripe in the middle of each petal. List each of Darwin’s postulates and what must be true about your population if it has undergone evolution by natural selection for petal color.QUESTION 9 Recent genetic research indicates that ____ or more individuals are needed for an endangered species to maintain its capacity for biological evolution. a. 100 b. 1,000 c. 10 d. 100,000 e. 10,000QUESTION 46 Which of the following statements about speciation is correct? a. Natural selection chooses the reproductive barriers for populations b. It always takes millions of years for speciation to occur c. The goal of natural selection is speciation d. Speciation is a process in which members become reproductively isolated into their own group.
- Question 3. There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following: A) The frequency of the recessive allele. B) The frequency of the dominant allele. C) The frequency of heterozygous individuals. Question 4 Within a population of butterflies, the colour brown (B) is dominant over the colour white (b).

Given this simple information, which is something that is very likely to be on an exam, calculate the following: A) The percentage of butterflies in the population that are heterozygous. B) The frequency of homozygous dominant individuals. Question 5 A rather large population of organisms have 396 red-sided individuals…QUESTION 50 You often hear that we evolved from monkeys.

Divergent populations that experience a sudden large migratory event will be immediately in LE after mixing. d.

Evolution is a completely random process. b. Evolution is synonymous with natural selection. c. Evolution only occurs in individuals. d. Evolution is defined as change in allele frequencies over time.Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. D) The frequency of the "A" allele. E) frequency of A is by definition equal to p, so the answer is 40%. F) The frequencies of the genotypes "AA" and "Aa." G)The frequencies of the two possible phenotypes if "A" is completely dominant over "a."
