The excessive use of pesticides has only resulted in the occurrence of more resistant varieties of pests rather than their complete eradication. How can you link this with Darwin’s theory of Natural Selection and Evolution?

The first clinical gene therapy was given in 1990 to a four-year-old girl suffering from Adenosine Deaminase Deficiency (ADA). Could you suggest a possible cure for such a disorder with the knowledge of gene therapy and its types?

For the experimental research, Dr. Ian Wilmut used the nucleus of the udder cell from a six-year-old Finn Dorset white sheep and preserved the diploid nucleus (2n). He took an ovum from the ovary of another sheep. The haploid ovum was removed. The diploid nucleus of the udder cell was injected into the cytoplasm of the enucleated ovum. Then the diploid nucleus ovum was implanted into the uterus of the surrogate mother sheep. The diploid ovum developed into a young one, named “Dolly”.

i) Why did Wilmut select the udder cell?

ii) Define the terms haploid and diploid.
