- a. DNA.
- b. RNA.
- c. plasmids.
- d. siRNA.

Introduction:
Single nucleotide polymorphism or SNPs are defined by the single nucleotide which is present repeatedly in the DNA sequences that cause genetic variation among individuals in a population.
Answer to Problem 1Q
Correct answer:
Single nucleotide polymorphism is found in DNA. Thereforeoption (a) is correct.
Option (a) is given as “DNA”.
Explanation of Solution
Justify reasons for the correct statement:
Single nucleotide polymorphism is characterized by the occurrence of a single nucleotide at specific positions in DNA. Single polymorphism among the DNA of different individual of same species is primary responsible for the different polymorphic appearance.
Hence, option (a) is correct.
Justify reasons for the incorrect statements:
Option (b) is given as “RNA”.
RNA is a single stranded structure and in the cell it is present in helical form and it does not contain any polymorphic forms. Hence, it is a wrong answer.
Option (c) is given as “plasmid”.
Plasmid is an extra chromosomal closed circular DNA which does not contain single polymorphism. Hence, it is a wrong answer.
Option (d) is given as “siRNA”.
The siRNA regulates the gene silencing in the cell, and does not occurs in polymorphic form. Hence, it is a wrong answer.
Hence, options (b),(c), and(d) are incorrect.
Single-nucleotide polymorphism is used as a genetic marker which indicates genetic variation among individuals in a population.

- Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.
