No! The true laws of heredity are "Danciu laws of heredity-four new laws"

If the parental forms are much less than the recombinant forms in a dihybrid testcross in sweetpea, it suggests that the two genes are physically linked on the same chromosome. This violates Mendel's principle of independent assortment. Bateson and Punnett's experiments supported Mendel's findings by showing a 9:3:3:1 ratio of offspring, providing evidence for independent assortment.

The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the recessive trait.
In the F2 generation, Mendel observed that the traits that had been masked in the F1 generation reappeared in a predictable ratio of 3:1 for the dominant and recessive traits, respectively. This led to the formulation of Mendel's law of segregation, which states that alleles segregate independently during gamete formation.
1- law of dominance. 2- law of segregation. 3-law of assortment .
Mendel discovered three principles of heredity: the Law of Segregation (allele pairs separate during gamete formation), the Law of Independent Assortment (genes for different traits are inherited independently), and the Law of Dominance (some alleles are dominant over others).
Yes, Mendel's observation that the genotypes of the F1 offspring exhibited a 9:3:3:1 ratio in his dihybrid cross experiment provided evidence for the independent assortment of genes. This ratio suggested that the two traits being studied were inherited independently of each other, supporting Mendel's principle of independent assortment.

9:3:3:1 was the ratio of Mendel's f2 generation for the two factor cross.

Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc

75% there will be TT, Tt, Tt, and tt. tt is going to be short. This means that 3/4 will be tall. 3/4 is 75%
