Fundamental genetics Welcome to your Fundamental genetics 1. None 2. Autosomal disorders, Are prominently observed in the female individuals Are dependent of the sex of the individual Follow the mendelian segregatio2 None 3. 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 4. Advantage/s of using bacterial system as a model for genetic studies is /are? Bacteria are fast dividing They take little space to grow They are convenient for mutagenesis All of the above None 5. Davis U tube experiment suggested that Auxotrophic mutants always have the capability to revert back to the wild type For genetic transfer the physical contact between two bacteria is essential When two auxotrophic bacterial cells were mixed Wild type bacteria could grow in the minimal medium because of “cross feeding” No physical contact is required for the genetic transfer between two bacteria None 6. What is plasmid? Plasmid is a self replicating extrachromosomal DNA commonly present in bacteria It can self replicate but it does not have its own origin of replication It has its own origin of replication It can recombine with the chromosomal DNA All of the above 1, 3, & 4 None 7. In genetics, which of the following is NOT applicable to the tester individual, Genetically homozygous recessive Used in test cross Help to determine genetic purity of the individual Has dioecious sexual make up None 8. Which of the following is the smallest chromosome in human cell? Y chromosome Chromosome 21 Chromosome 22 Chromosome 20 None 9. Autosomal disorders can be, Dominant Recessive Polymorphic All of the above None 10. Allelic variation contributes to continuous as well as discontinuous variation in the population, True False None Please fill in the comment box below. Time's up
