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.

-Hot desert biome
Explanation;
Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.
-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
