Question:
Name the Mendel’s factors and pair of contrasting traits
Name the Mendel’s factors and pair of contrasting traits
Show Hint
Mendel’s "factors" = genes; Contrasting traits (e.g., tall/dwarf) = controlled by alleles.

The Correct Option is B
Approach Solution - 1
Gregor Mendel, through his experiments on pea plants, proposed the existence of "factors" that control traits. These factors are now known as genes.
- The factors (genes) Mendel referred to are inherited units that control traits.
- Alleles are the alternate forms of a gene, responsible for the pair of contrasting traits (e.g., tall vs. dwarf, round vs. wrinkled seeds).
Thus:
- Mendel’s "factors" = Genes
- Mendel’s "pair of contrasting traits" = Controlled by Alleles
- The factors (genes) Mendel referred to are inherited units that control traits.
- Alleles are the alternate forms of a gene, responsible for the pair of contrasting traits (e.g., tall vs. dwarf, round vs. wrinkled seeds).
Thus:
- Mendel’s "factors" = Genes
- Mendel’s "pair of contrasting traits" = Controlled by Alleles

Approach Solution -2
Name the Mendel’s factors and pair of contrasting traits:
Gregor Mendel, known as the father of genetics, conducted pioneering experiments on pea plants to understand the inheritance of traits. He proposed that traits are controlled by discrete units called "factors," which are now known as genes.
Each gene exists in different forms called alleles. These alleles occur in pairs, with one inherited from each parent. Mendel observed that these pairs of contrasting traits (alleles) determine the characteristics expressed in the offspring.
For example, the gene for plant height has two alleles: one for tallness and one for dwarfness. These alleles are contrasting traits that segregate independently during gamete formation.
Thus, Mendel's "factors" are genes, and the pairs of contrasting traits are alleles.
Correct Answer: Genes and Alleles
