Biomass turnover time is the ratio between biomass and productivity of an ecosystem. Which of the following forests should have highest biomass turnover time? Tropical wet forests Temperate deciduous forests Tropical dry forests Boreal forests2. The rate of molecular evolution would be least in: Flanking regions of genes Synonymous change in codon Nonsynonymous change in codon Introns of genes3. In a population with two alleles ‘b’ and ‘B’ having allele frequency 0.7 and 0.3 in Hardy‐Weinberg equilibrium, how many individuals in a sample of 250 can be expected to be heterozygous (bB)? 21 105 52 424. If all organisms in a population are triploid , then Hardy-Weinberg theorem applicable will be: (p+q+r)^3 (p+q)^3 (p+q+r)^2 (p+q)^25. Sustainable harvesting of a fish population growing logistically is done at: At lowest level At half of the carrying capacity Above carrying capacity At the carrying capacity6. In sexually reproducing organisms which is the most important barrier for the speciation? Reproductive barrier Geographical barrier Temporal barrier Ethological barrier7. A plant with genotype r+h+/ r‐h‐ was test crossed. Out of the total 280 progenies, 260 are r+h+/ r‐h‐ and r‐h‐/ r‐h‐. Then the recombination frequency will be: 92.8 3.6 7.14 46.48. Change in the allele frequency at species or below species level can be termed as: Silent evolution Microevolution Macroevolution Mega evolution 9. Which factor is least responsible for genetic drift? Restriction of resources Bottleneck Migration Founder effect10. In a hybridization experiment, a plant shows phenotypic ratio of 15:1. How many genes control the trait for observed phenotypic ratio? Three Two Polygene One 11. Genetic mapping reveals that distance between two genes ‘A’ and ‘B’ is 10 cM. What is the chance of getting Aabb progeny if AaBb is test crossed? 10 % 5 % 45 % 90 %12. In a population of 10 million individuals birth rate is 19 per 1000 and death rate is 14 per 1000. The annual rise in the population would be: 5,000 500,000 14,000 50,00013. In spite of the prevalence of herbivory, the earth continues to be largely green because: The number of herbivore species is low. Herbivore numbers are kept low by their predators. Herbivores are very inefficient feeders. Herbivory promotes chlorophyll development in plants14. The most probable limiting factor for primary productivity in an aquatic ecosystem is: Phosphorus Nitrogen Sulfur Carbon15. The C-value paradox suggest the: Non-colinearity between genome size and complexity of organism Dosage compensation Co-linearity between genome size and complexity of organism Number of chromosomesYou have reached at the End of this Mock Test.
