Q. 82. Two genes R and Y are located very close on the chromosomal linkage map of maize plant. When RRYY and rryy genotypes are hybridized, the F2 segregation will show:
a. Higher number of the parental types.
b. Higher number of the recombinant types.
c. Segregation in the expected 9: 3: 3: 1 ratio.
d. Segregation in 3:1 ratio.
Sol. When the linked genes are situated quite close, the chances of crossing over are highly reduced. Due to this, large number of parental gametes are formed and only few recombinant gametes are formed. This results in higher number of parental types in F2 generation as compared to recombinants. Correct choice: (1)

a. 3 : 1
b. 50 : 50
c. 9 : 1
d. 1 : 3
Sol. This is a monohybrid test cross. Correct choice: (2)
Q. 86. The length of DNA molecule greatly exceeds the dimensions of the nucleus in eukaryotic cells. How is this DNA accommodated?
a. Through elimination of repetitive DNA.
b. Deletion of non-essential genes.
c. Super-coiling in nucleosomes.
d. DNAse digestion.
Sol. The nucleosome model explains the packaging of histone proteins and DNA in the chromatin material which forms the chromosome. Correct choice: (3)
Q. 87. In cloning of cattle a fertilized egg is taken out of the mother’s womb and:
a. from this upto eight identical twins can be produced
b. the egg is divided into 4 pairs of cells which are implanted into the womb of others cows
c. in the eight cell stage, cells are separated and cultured until small embryos are formed which are implanted into the womb other cows.
d. in the eight cell stage the individual cells are separated under electrical field for further development in culture media.
Sol. As per the experiment performed by the scientist from Japan. Correct choice: (3)
Q. 88. Which one of the following statements is correct?
a. At present it is not possible to grow maize without chemical fertilizers.
b. Extensive use of chemical fertilizers may lead to eutrophication of nearby water bodies.
c. Both Azotobacter and Rhizobium fix atmospheric nitrogen in root nodules of plants.
d. Cyanobacteria such as Anabaena and Nostoc are important mobilizers of phosphates and potassium for plant nutrition in soil.
Sol. The Agricultural run off contains high concentration of chemical fertilizers. Which is discharge in near by lakes causes nutrient enrichment of lakes called eutrophication. Correct choice: (2)
