Homozygous for tall is TT Homozygous for short is tt All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
purple is dominant over white in Mendel's pea plant experiment, meaning that the offspring inherited at least one purple allele from the purple parent. This resulted in all the offspring showing the purple trait.
All offspring would be heterozygous for the gene controlling plant height. This is because if alleles do not segregate, they remain together and are passed on as a unit. The offspring plants would all be tall because the allele for tallness is dominant over the allele for shortness.

The offspring of two true-breeding plants is also true-breeding, meaning they will consistently display the same traits as the parents. This is because true-breeding plants are homozygous for a particular trait, so when they are crossed, their offspring will also be homozygous for that trait.
because it helped Mendel discover which plants would be crossed to produce offspring.
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.

Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
