In sexually reproducing organisms which is the most important barrier for the speciation? Temporal barrier Geographical barrier Ethological barrier Reproductive barrier2. 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 dry forests Tropical wet forests Boreal forests Temperate deciduous forests3. Change in the allele frequency at species or below species level can be termed as: Silent evolution Microevolution Mega evolution Macroevolution4. The C-value paradox suggest the: Co-linearity between genome size and complexity of organism Non-colinearity between genome size and complexity of organism Dosage compensation Number of chromosomes5. In spite of the prevalence of herbivory, the earth continues to be largely green because: Herbivores are very inefficient feeders. Herbivory promotes chlorophyll development in plants The number of herbivore species is low. Herbivore numbers are kept low by their predators.6. Sustainable harvesting of a fish population growing logistically is done at: At half of the carrying capacity At the carrying capacity At lowest level Above carrying capacity7. 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 % 45 % 90 % 5 % 8. The most probable limiting factor for primary productivity in an aquatic ecosystem is: Phosphorus Sulfur Nitrogen Carbon9. 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: 14,000 5,000 50,000 500,00010. Which factor is least responsible for genetic drift? Migration Bottleneck Restriction of resources Founder effect11. 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: 46.4 3.6 7.14 92.812. 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)? 52 21 42 10513. If all organisms in a population are triploid , then Hardy-Weinberg theorem applicable will be: (p+q+r)^2 (p+q)^2 (p+q+r)^3 (p+q)^3 14. In a hybridization experiment, a plant shows phenotypic ratio of 15:1. How many genes control the trait for observed phenotypic ratio? One Three Polygene Two15. The rate of molecular evolution would be least in: Nonsynonymous change in codon Flanking regions of genes Introns of genes Synonymous change in codonYou have reached at the End of this Mock Test.
