Question
1. Ira population with two alileles is at Hardy-Weinberg equilibrium and the fregueney of one allele is 0.7, what is the heterozygote frequency? A) 0.7 B) 0.42 C) 0.3 D) 0.21 E) Insufficient information is given to answer the question. 2. All of the plants living at a particular time or place are called A) the biota. B) the flora. C) the fauna. D) the igneous species. E) Gondwana. 3. Assuming that there are only two alleles at a given locus, if the frequency of one allele is 0.77, what is the frequency of the other allele? A) 0.4 B) 0.23 C) 0.6 D) 1 D) Insurficient information i iven to answer the question 4. Abnormally high concentrations of which of the following elements have been found in rocks dating from the end of the Cretaceous? A) Lithium B) Mercury C) Iridium D) Nickel E) Tungstern 5. Rocklike structures formed by the oxygen-generating cyanobacteria are known as A) strata. B) stromatolites. C) igneous. D) lithospheric. E) rift valleys.Explanation / Answer
1. Let us assume, p=0.7
According to HWE, q=1-p = 1-0.7=0.3
Heterozygous frequency = 2pq = 2*0.7*0.3 = 0.42
ANSWER: B) 0.42
2. Biota: Reffering to both animals and plants of particular period.
Flora: Reffering to plants of particular period.
Fauna: Reffering to animals of particular period.
ANSWER: B) flora
3. p = 0.6
q = 1-p = 1-0.6 = 0.4
ANSWER: A) 0.4
