#1. The mechanism that causes a gene to move from one linkage group to another is called
#2. Which of the following phenomena leads to variation in DNA?
Mutation → Sudden change in genetic Material
Recombination → Non-parental combination
#3. Alleles are
Alleles are slightly different molecular forms of the same gene.
#4. The experimental proof for semiconservative replication of DNA was first shown in a
Semi-conservative DNA replication was first shown in Bacterium Escherichia coli by Matthew Meselson and Franklin Stahl.
#5. The final proof for DNA as the genetic material came from the experiments of
Hershey and Chase gave unequivocal proof which ended the debate between protein and DNA as genetic material.
#6. Removal of introns and joining of exons in a defined order during transcription is called
#7. Which one of the following are analogous structures?
Gills of prawn and lungs of man have different origin.
#8. All genes are located on the same chromosome
NCERT Class 12 Page No.83
A linkage group can be defined as all the genes on a single chromosome that move as a unit during the cell division. These genes do not tend to separate, until the crossing-over and if the distance between them is very less, they will not undergo the crossing-over
#9. Conditions of a karyotype 2n ± 1 and 2n ± 2 are called
NCERT Class 12 Page No.91 & 92 (Checkout Chromosomal Disorder)
The chromosomal disorders are caused due to lack or additions or abnormal arrangement of one or more chromosomes. Failure of segregation of chromatids during cell division cycle results in the gain or loss of chromosome(s), is called aneuploidy
#10. Distance between the genes and percentage of recombination shows
#11. If a genetic disease is transferred from a phenotypically normal but carrier female to only some of the male progeny, then the disease is
#12. In sickle cell anaemia, the glutamic acid is replaced by valine. Which one of the following are triplet codes for valine?
NCERT Class 12 Page No.90 (Fig 5.15)
#13. A person having genotype IA IB would show the blood group as AB. This is because of
NCERT Class 12 Page No.77 (5.2.2.2) and Don’t forget to Read Table 5.2
#14. ZZ/ZW type of sex determination is seen in
NCERT Class 12 Page No.86 (Figure 5.12 C)
#15. A cross between two tall plants resulted in an offspring having few dwarf plants. What would be the genotypes of both the parents?
#16. In a dihybrid cross, if you get 9 : 3 : 3 : 1 ratio, it denotes that
#17. Which of the following will not result in variations among siblings?
Linkage will not result in variations among siblings because linked genes occur on the same chromosome and are transmitted together. In linkage there is a tendency to maintain the parental gene combinations except for occasional crossovers.
#18. Mendel’s Law of independent assortment holds good for genes situated on the
#19. Occasionally, a single gene may express more than one effect. This phenomenon is called
NCERT Class 12 Page No.85 (5.5 2nd Line)
#20. The inheritance pattern of a gene over generations among humans is studied by the pedigree analysis. Character studied in the pedigree analysis is equivalent to
NCERT Class 12 Page No.88 (5.8 1st Paragraph)
#21. In the F2 generation of a Mendelian dihybrid cross, the number of phenotypes and genotypes are
