### Step-by-Step Text Solution for "Polymorphism" **Step 1: Understanding the Concept** - Polymorphism refers to the ability of a substance to exist in more than one crystalline form. This phenomenon is significant in chemistry and materials science. **Step 2: Definition of Polymorphism** - Polymorphism is defined as the phenomenon where a single substance can crystallize into two or more different forms. These forms arise under varying conditions of solidification, such as temperature and pressure. ...

Assertion (A): DNA fingerprinting is applied in paternity testing in case of disputes. Reason(R): It employs the principle of polymorphism in DNA sequences as polymorphisms are inheritable from parent to children.

Assertion. DNA fingerprinting is very well known for its application in paternity testing is case of disputes. Reason. It employs the principle of polymorphism in DNA sequences as the polymorphisms are inheritable from parents to children

Assertion :- DNA fingerprinting involves identifying differences in some specific regions in DNA called as repetitive DNA sequences. Reason : These sequences show high degree of polymorphism & from the basis of DNA fingerpringing.

Assertion :- The probability of DNA polymorphism would be higher in non-codeing DNA sequences. Reason : Mutations in these seuqences may not have any immediate effect in an individual's reproductive ability.

Three copies of chromosome 21 in a child with Down's syndrome have been analysed using molecular biology technology to detect any possible DNA polymorphism with reference to different alleles located on chromosome 21. Results showed That out of 3 copies 2 of the chromosomes of the child contain the same alleles as one of the mother's alleles. Based on this when did the non-disjunction event most likely occur?
