Mcqs On Mendel Laws Of Inheritance

Gregor Johann Mendel is widely regarded as the “Father of Modern Genetics” for his pioneering work in the field of genetics. He developed three laws of inheritance, namely Law of Dominance, Law of Segregation, and Law of Independent Assortment. He conducted his experiments on garden pea plants with contrasting characteristics and performed self-pollination and cross-pollination to study the inheritance patterns of traits.

After self-fertilization of the F1 generation, which was the result of cross-fertilization between true-breeding tall and dwarf plants, the resultant plants had a genotype ratio of 3 tall: 1 dwarf.

(a) 1:2:1 (homozygous tall : heterozygous tall : dwarf)

(a) 1:2:1 (homozygous tall : heterozygous tall : dwarf)

(b) 1:2:1 (heterozygous tall : homozygous tall : dwarf)

(c): Tall : Dwarf (3:1)

(d) Dwarf : 3, Tall : 1

Question: What is the answer to (a)?

Answer: (a)

2. Which of the following characteristics was not studied by Mendel in his experiments with pea plants?

(b) Seed Shape

(c) Pod Length

(d) Flower Position

Which of the following is true?

(a) 2 + 2 = 5
(b) 2 + 2 = 3
(c) 2 + 2 = 4

Answer: (c)

3. Mendel studied two contrasting characteristics of pea plants.

(a) Eight

(b) Seven

(c) Six

(d) Five

Which of the following is correct?

(a) The sky is green
(b) The sky is blue

Answer: (b)

If the F2 generation shows a ratio of 1:2:1 for both genotype and phenotype, it indicates

Incomplete Dominance in Monohybrid Cross

(b) Complete Dominance in Monohybrid Cross

(c) Dihybrid Cross

(d) Co-dominance

What is the capital of France?

Answer: (a) The capital of France is Paris.

5. Cross-Testing

Whether two traits are linked or not

(b) The genotype of F2 plant

(c) Whether the two species will breed successfully or not

(d) Number of Alleles in a Gene

Which of the following is correct?

(a) This is incorrect
(b) This is correct

Answer: (b)

6. The genotype of a dominant plant can be identified through observation of its phenotype.

Pedigree Analysis

(b) The moon is the biggest planet
(c) The Earth is the biggest planet

Answer: (c)

7. Test Cross is a type of breeding experiment

(a) Cross between two recessive homozygotes

(b) Cross between a dominant homozygote and a heterozygote

(C) Cross Between Two F1 Hybrids

(d) Cross between an F1 Hybrid and a Recessive Homozygote

Which of the following is the correct answer?

(a) Option A
(b) Option B
(c) Option C
(d) Option D

Answer: (d) Option D
