Some so called doctors claim that their medicines provide 100% guarantee for getting a son or a daughter according to the wish of the parent. How do you react to such claims on the basis of your knowledge of genetics? Give a suitable explanation.

Offspring formed by sexual reproduction exhibit more variation than those formed by Asexual reproduction because. (A) Sexual reproduction is a lengthy process. (B) Gametes of parents have qualitatively different genetic composition. (C) Genetic material comes from parents of two different species. (D) Greater amount of DNA is involved in sexual reproduction.

Assertion (A): Gametes formed from the same individual have exactly identical DNA. Reason (R ): Homologous chromosomes are formed by DNA replication.

Find out which among the following is true and which is false (i) Recombinant DNA technology has made it possible to engineer microbes, plants and animals such that they have novel capabilities. (ii) Genetically modified organisms have been created by using methods other than natural methods to transfer one or more genes from organism to another, generally using techniques such as recombinant DNA technology. (iii) GM plants have been useful in increasing crop yields, reduce post harvest losses and make crops more tolerant of stressess. (iv) Recombinant DNA technology process have made immense impact in the area of healthcare by enabling mass production of safe and more effective therapeutics. (v) since the recombinant therapeutics are identical to human proteins, they do not induced unwanted immunological responses.
