Fundamental genetics Welcome to your Fundamental genetics 1. 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 2. Allelic variation contributes to continuous as well as discontinuous variation in the population, True False None 3. Mitosis is a cell division associated with asexual reproduction of Somatic cells. True False None 4. Autosomal disorders, Are prominently observed in the female individuals Are dependent of the sex of the individual Follow the mendelian segregatio2 None 5. Which of the following is NOT true about the Sutton-Bovery theory of chromosomes? Mendel’s observations were matching with the behaviour of the chromosomes during meiosis Sutton-Boveri theory suggests that genes are located on the Chromosomes Suttone-Bovery theory was proved with the direct evidence None of the above None 6. Which of the following is true about genome sequencing and mapping, Genome sequencing can identify the genes, their function as well as define their position Most of the genes identified by the genome sequencing are of unknown function Gene mapping helps to associate the phenotypic data with the gene sequences All of the above 2 & 3 None 7. Autosomal disorders can be, Dominant Recessive Polymorphic All of the above None 8. 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 9. 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 10. Which of the following scientific approach used by Mendel was/were crucial in his experimentation? Using a pea plant for experimentation because it has short life span Obtaining a pure line for each characters in the beginning of the studies Counting the number of progenies with associated characters All of the above 2 & 3 None Please fill in the comment box below.
