​Let's go back to the topic about "Monohybrid Cross"

​The mystery of genetics was unlocked during the mid-nineteenth century by Gregor Mendel. He conducted an experiment on pea plants by cultivating pea plants and observing the pattern of inheritance in different stages of generation.

​Mendel investigated the pairs of pea plants with one contrasting trait. Mendel studied the following seven characters with contrasting traits:

• Flower colour: Violet/white

• Flower position: Axial/terminal

• Pod colour: Green/yellow

• Pod shape: Inflated/constricted

• Seed colour: Yellow/green

• Seed shape: Round/wrinkled

• Stem height: Tall/dwarf

Monohybrid Cross Definition

​“A monohybrid cross is the hybrid of two individuals with homozygous genotypes which result in the opposite phenotype for a certain genetic trait.”

“The cross between two monohybrid traits (TT and tt) is called a Monohybrid Cross.”

Monohybrid cross is responsible for the inheritance of one gene. It can be easily shown through a Punnett Square.

Monohybrid cross is used by geneticists to observe how homozygous offspring express heterozygous genotypes inherited from their parents.​

Monohybrid Cross Definition

Gregor Mendel’s Peas

For monohybrid cross, Mendel began with a pair of pea plants with two contrasting traits, i.e., one tall and another dwarf. The cross-pollination of tall and dwarf plants resulted in tall plants. All the hybrid plants were tall. He called this as a first hybrid generation (F₁) and offspring were called Filial₁ or F₁ progeny.

Let's watch a video here:

​

Monohybrid Cross Definition

​He continued his experiment with self-pollination of F₁ progeny plants. Surprisingly, he observed that one out of four plants were dwarf while the other three were tall. The tall and the short plants were in the ratio of 3:1.
