Inheritance Biology Practice Test |CSIR UGC NET JRF Life Sciences Exam

1.All of the Mendelian alleles for different traits showed
Epitasis
Co dominance
Incomplete dominance
Dominance and recessiveness

2.In a genetc 9:7 ratio in F2 generation represents
Epistasis
co-dominance
incomplete dominance
complete dominance

3.A cross is made between two plants with white flowers. All the F1 progeny had red colored flower. This is because of
reversion
translocation
reversion
complementation

4.A gene inherited from mother is not expressed in the offspring, but the same gene when inherited from father is expressed in both male and female offspring. This phenomenon is the hallmark of gene
silencing
recombination
delection
imprinting

5.Dosage compensation in mammal females is achieved by
Methylation of one x chromosome
Hyper activation of one x chromosome
Elimination of one x chromosome
Hypoactivation of Both X chromsome

6.Criss-cross inheritance is shown by
Sex linked traits
Sex influenced traits
Sex limited traits
Autosomes

7.Ratio of observed double crossover frequency to the expected frquency to the expected frequency of double crossover gamaete during three point test cross is termened as
Coefficient of variance
Coefficient of suppression
Coefficient of Coincidence
Coefficient of interference

8.Molecular marker cannot be utilised for
mapping of genes
Identifying the clones
Identifying the locus of gene on chromosome
Identifying the expressed product

9.Extra-chromosomal inheritance can be dected by
Back cross
Test cross
Reciprocal cross
Dihybrid cross

10.The distance between bacterial genes as determined from interrrupted mating experiments are measured in units of
cM
minutes
bp
micromeeters
