Question 1: Shorthorn breed was evolved byRobert BakewellBatesonD.S.FalconerCharles Coling Question 2: Methods of Selection were given byHazel and LushSewall and LushFalconer and LushSewall and Falconer Question 3: Generation interval increases inIndividual SelectionPedigree selectionProgeny SelectionTandem selection Question 4: Correlated characters were explained byWilliam BatesonSewall WrightD.S.FalconerG.J.Mendel Question 5: Repeatability of a trait isLower limit of heritabilityUsed to predict MPPANon genetic factorConstant Value Question 6: Accuracy of Progeny selection is more valuable than mass selection becauseGeneration interval is increasedAccuracy of estimating breeding value can be increasedIt can be used for low repeatable traitsLess time consuming Question 7: Barred condition is seen inCattleSheepDrosophilaChickens Question 8: One of the following is a not a systematic processSelectionMigrationMutationRandom drift Question 9: Which of the following statement is correct? The selection intensityDoes not depend upon the heritability valueSame for males and femalesIs more when more animals are selectedDepends upon the phenotypic mean Question 10: Panmixia meansAssortive mating Random mating Non random matingInterse mating Question 11: In Kengurii sheep, the selection differential for 6 months body weight is 2 kg and response to selection is 0.8 kg then the realized heritability for the trait will be0.40.480.61 Question 12: Positive assortive mating results inIncrease in HeterozygosityDecrease in HeteozygosityHeterozygosity remains same Homozygosity remains same Question 13: The number of sperms resulting from one primary spermatocytes is612184 Question 14: Lemarkism theory was invalidated byDarwinWeismannLemarkSchwann Question 15: The phenotype is not a good indicator of genotype when heritability of a trait is1highmoderatezero Question 16: Bull dog is a lethal condition observed inDogCattleSheepGoat Question 17: One of the following is not a non sense codonUAGUAAAUGUGA Question 18: Selection response increases whenHeritability decreasesAdditive genetic variance increasesSelection differential decreasesStandard deviation decreases.
