The ratio obtained is 9:3:3:1 in which parental as well as new
combinations are observed. This indicates that progeny plants have not
inherited a single whole gene set from each parent.
Every germ cell takes one chromosome from the pair of maternal and
paternal chromosomes. When two germ cells combine, segregation of
one pair of characters is independent of other pair of characters
combinations are observed. This indicates that progeny plants have not
inherited a single whole gene set from each parent.

Analysis of Mendel's Experiment on Pea Plants
Mendel's experiment on pea plants resulted in the following types of seeds:
- Round, yellow: 630
- Round, green: 216
- Wrinkled, yellow: 202
- Wrinkled, green: 64
Mendel observed that the ratio of the phenotypic traits was approximately 3:1 for the dominant and recessive traits, indicating that there was a predictable pattern of inheritance. This led him to propose the law of segregation and the law of independent assortment, which together form the basis of modern genetics.
Mechanism of Inheritance
The mechanism of inheritance that explains these results is based on the principles of dominance, segregation, and independent assortment.
Dominance:
Mendel observed that when a pea plant with two different alleles for a trait (e.g., round and wrinkled) is self-fertilized, one allele (the dominant allele) is expressed in the phenotype, while the other allele (the recessive allele) is not. In this case, the round allele is dominant over the wrinkled allele, and the yellow allele is dominant over the green allele.
Segregation:
Mendel observed that during the formation of gametes, the two different alleles for a trait segregate from each other so that each gamete receives only one allele. This results in a 1:2:1 genotype ratio and a 3:1 phenotypic ratio in the offspring.
Independent Assortment:
Mendel observed that the inheritance of one trait is independent of the inheritance of another trait. This is known as independent assortment. In this case, the inheritance of seed shape (round or wrinkled) is independent of the inheritance of seed color (yellow or green).
Conclusion
Mendel's experiment on pea plants provided the foundation for our understanding of the mechanism of inheritance. His principles of dominance, segregation, and independent assortment are still applicable today and have been used to explain a wide range of genetic phenomena.
