Inheritance Biology MCQs Part 1

1. The resemblance of individuals to their progenitors is called

• heredity
• genetics
• evolution
• none of these

2. Mendel formulated some laws which are known as

• Laws of germplasm
• Laws of origin of species
• Laws of recapitulation
• Laws of inheritance

3. Which of the following is dominant character according to Mendel?

• Dwarf plant and yellow fruit
• Terminal fruit and wrinkled seed
• White testa and yellow pericarp
• Green coloured pod and rounded seed

4. The alleles are

• a pair of genes governing a specific character such as tallness or dwarfness
• multiple forms of genes
• genes governing eye characters
• genes present in allosomes

5. When a true breeding pea plant that has yellow seeds is pollinated by a plant that has green seeds, all the F1 plants have yellow seeds. This means that the allele for yellow is

• heterozygous
• dominant
• recessive
• lethal

6. In Mendel’s experiment, nature of seed coat, flower colour, position of flower, pod colour, stem height, etc. are referred to as

• alleles
• genotypes
• phenotypes
• all of above

7. An organism with two identical alleles for a given trait is

• homozygous
• segregating
• dominant
• a hermaphrodite

8. Organisms phenotypically similar but genotypically different are said to be

• heterozygous
• monozygous
• multizygous
• homozygous

9. Which of the following cross will give recessive progeny in F1 generation ?

• TT × tt
• Tt × TT
• tt × tt
• TT × TT

10. When Mendel crossed true breeding whiteflowered strain of peas with a true breeding red-flowered strain, individuals in the F2 represented [DPMT 1976]

• white-flowered plants
• red-flowered plants
• red-flowered and white-flowered plants in the ratio 3 : 1
• red and white-flowered individuals in the ratio 1 : 1
