उत्तर
| Monohybrid | Dihybrid |
| Crosses involving a single pair of alleles. It yields a phenotypic ratio of 3 : 1 in F2 generation. | Crosses involving two pairs of alleles. It yields a phenotypic ratio of 9 : 3 : 3 : 1 in F2 generation. |

When a cross is made between tall plant with yellow seeds (TtYy) and tall plant with green seed (Ttyy), what proportions of phenotype in the offspring could be expected to be:
- Tall and green.
- Dwarf and green.
What is a monohybrid cross? How did Mendel perform this cross?
Pure-bred tall pea plants are first crossed with pure-bred dwarf pea plants. The pea plants obtained in the F1 generation are then selfed to produce F2 generation of pea plants.
What is the ratio of tall plants to dwarf plants in the F2 generation?
Pure-bred tall pea plants are first crossed with pure-bred dwarf pea plants. The pea plants obtained in the F1 generation are then selfed to produce F2 generation of pea plants.
Which type of plants was missing in the F1 generation but reappeared in the F2 generation?
Differentiate between inherited and acquired characters. Give one example for each type.
Monohybrid crosses are useful in demonstrating which of the following laws of inheritance suggested by Mendel?
Which pair of contrasting characters is studied in the pea plant monohybrid cross?
Mendel used a monohybrid cross to understand how which feature passes from parents to offspring?
