Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
A Punnett square reveals that two heterozygous organisms will yield a progeny with 75% displaying the dominant phenotype. 50% of the progeny will be heterozygous, and the other half will be homozygous.
This diagram shows Mendel's first experiment with pea plants. The F1 generation results from cross-pollination of two parent (P) plants, and contained all purple flowers. The F2 generation results from self-pollination of F1 plants, and contained 75% purple flowers and 25% white flowers
The trait that is being studied is the height of the pea plants.
Mendel's experiments show that the Traits may be dominant or recessive by performing a monohybrid cross. Monohybrid cross between two pure breeding varieties always obtained hybrid progeny exhibiting one parental trait while the opposite trait was never expressed in the F1 generation.
