Sample Questions

1mcq

The plant used by Mendel for his genetic experiments was:

Show answer

Pisum sativum

Mendel used Pisum sativum (garden pea) for his genetics experiments, studying 7 pairs of contrasting traits over 8 years.

2mcq

In a monohybrid cross, the F2 phenotypic ratio is:

Show answer

3:1

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

3mcq

The F2 phenotypic ratio in a dihybrid cross is:

Show answer

9:3:3:1

In a dihybrid cross (two independent traits), the F2 phenotypic ratio is 9:3:3:1, demonstrating Mendel's Law of Independent Assortment.

4mcq

Mendel's Law of Segregation states that:

Show answer

The two alleles of a gene separate during gamete formation

The Law of Segregation (Purity of Gametes) states that the two alleles of a gene separate during meiosis, so each gamete carries only one allele.
