Sample Questions

1multiple correct

Which of the following are reasons why Mendel selected garden pea for his experiments?

Show answer

Annual plant with short life span, Seven pairs of contrasting characters, Self-pollinated and can be cross-pollinated, High yield

Mendel selected garden pea because it is an annual plant (short life span), has seven pairs of easily detectable contrasting characters, is self-pollinated but can be cross-pollinated, and has high yield. Being expensive was not a reason for selection.

2multiple correct

Which nitrogenous bases are purines in DNA?

Show answer

Adenine, Guanine

Purines are double-ringed compounds in DNA. Adenine and Guanine are purines. Cytosine and Thymine are pyrimidines (single-ringed compounds).

3multiple choice

In humans, which parent determines the sex of the child?

Show answer

Father

In humans, the father determines the sex of the child because males produce two types of sperms (22+X and 22+Y), while females produce only one type of ovum (22+X). The type of sperm that fertilizes the ovum determines the child's sex.

4multiple choice

What is the phenotypic ratio in F2 generation of a monohybrid cross?

Show answer

3:1

In a monohybrid cross, the phenotypic ratio in F2 generation is 3:1 (dominant:recessive). The genotypic ratio is 1:2:1. The 9:3:3:1 ratio is for dihybrid cross.
