Generally speaking, the letters used to represent cross breeding in Punnett squares indicate the characteristic being bred for. In this case, T would represent the tall plants, and S would represent the short plants. Cross-bred plants would most likely be represented by TS.
Yes, Mendel's principles of inheritance, such as the law of segregation and the law of independent assortment, apply to many other organisms beyond pea plants. These principles have been found to hold true in various animals, plants, and even humans, demonstrating their widespread relevance in genetics.
Morgan's research with fruit flies helped explain Punnett's and Bateson's observations of pea plants by providing evidence for the chromosomal theory of inheritance. Morgan discovered that traits are located on specific chromosomes and are inherited in a predictable manner, similar to Mendel's principles of segregation and independent assortment. This supported Punnett's and Bateson's observations by showing that genetic factors are physically located on chromosomes and are passed on through the process of meiosis.
P1 or parental
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
The Punnett square is a tool used in genetics to predict the outcomes of offspring based on the genotypes of the parents. For example, when crossing two pea plants with the genotypes Rr (round seeds) and rr (wrinkled seeds), a Punnett square can be used to show the possible combinations of alleles in the offspring.
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.
True breeding tall plants would be TT and true breeding short plants would be tt, so TT x tt would illustrate the crossbreeding.

TT x tt
The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
they were all hybrids
There were three times as many tall plants as short plants.
Three times as many shorts plants as tall plants.
