Active transport could transport material across the membrane against the concentration gradient
Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.
- A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
- True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
- These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
- The other allele, referred to as the recessive one, has no effect.
According to the given cross:
TT X tt (parents)
Tt Tt Tt Tt (offspring) all tall
Hence the percentage of dwarf individuals is 0.
