Question

What happened in Mendel’s experiments when a pea plant received two different alleles for the same trait?

Answer 1

Answer: The correct answer is C. The recessive allele was hidden by the dominant allele.

Alleles are the different forms of a gene, which correspond to a specific trait of the organism. They can be dominant ( generally denoted by capital letter) or recessive ( denoted by small letter).

The dominant allele expresses itself even in heterozygous ( like Tt fall tallness) state whereas recessive expresses itself when present only in the homozygous state ( tt for dwarfness).

In Mendel’s experiments when a pea plant received two different alleles for the same trait, the recessive allele was hidden by the dominant allele.

Answer 2

C. The recessive allele was hidden by the dominant allele.
