Consider the following statements and choose the correct answer:
1. Since chromosomal aberrations result in a change in the organism, they are also called chromosomal mutation
2. Chromosomal aberrations are of four types deletion, duplication, inversion and translocation
3. If a single break occurs near the end of a chromosome, it results in an intercalary deletion
4. A deficiency involves loss of a chromosome section
If two breaks occur in one chromosome, and one in a non-homologous one, the fragment from the first chromosome may become joined in an intercalary position in the second chromosome. This is a case of

If first four letters of the general english alphabet series are written in reverse order; again next 5 letters are written in reverse order; again next 6 letters are written in reverse order; again next 7 letters are written in reverse order, then what will be the 7th letter to the left of the 8th letter from the right?
The letters P, Q, R, S, T and U are to be placed one per vertex on a regular convex hexagon, but not necessarily in the same order. Consider the following statements: The line segment joining R and S is longer than the line segment joining P and Q. The line segment joining R and S is perpendicular to the line segment joining P and Q. The line segment joining R and U is parallel to the line segment joining T and Q. Based on the above statements, which one of the following options is CORRECT?
Which of the following is/are true? i. All children will inherit an X chromosome from their mothers. ii. All children will inherit a Y chromosome from their mothers. iii. A child who inherits an X chromosome from the father will be a boy. iv. A child who inherits an X chromosome from the father will be a girl.
When a part of one chromosome is joined to a part of different chromosome, the aberration is called
Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
