Fundamental genetics Welcome to your Fundamental genetics 1. What are prototrophic bacteria? Prototrophic bacteria can grow on minimal medium Prototrophic bacteria are those which require the medium supplemented with special growth promoting nutrients The bacteria those require antibiotics for growth. All of the above I and II None 2. In WZ pattern of inheritance male parent bear the ZZ pair of chromosomes and female parent bear the WZ pair. True False None 3. None 4. The total length of the DNA in each human cell is 2 meters 2X10 13 meters 1 meter 0.0006 mm None 5. Which of the following does not contribute to the differences between the individuals of the same species are primarily attributed to Allelic variation Mutations in particular genes Influence of the environment Genetic drift None 6. Which of the following is possible through controlled mating studies? Identification of Genes and their alleles Identification of the relative chromosomal locations of the genes Inheritance pattern of the genes All of the above None 7. In a genetic disorder person bears a copy of the mutant allele but fail to show phenotypic implications of the disorder which is otherwise life threatening, because, Individual posses suppressor mutation The individual is haplosufficient The metabolic alterations caused by the mutation are counterbalanced homeostasis All of the above None 8. Auxotrophic mutants are Able to grow on minimal medium Are the mutants produced after the transfer of the genetic material from donor to recipient Fail to grow unless and until supplied with one or more specific nutritional factor The one who posses the antibiotic resistance plasmid None of the above.
