Answer: one offspring out of the four will have a recessive-recessive genotype.
Explanation: A cross between two parents who are heterozygous for a gene that has a simple dominant-recessive pattern of inheritance will produce four offsprings: one will be homozygous dominant, two will be heterozygous dominant while one will be homozygous recessive.
Homozygous dominant offspring has two dominant alleles, heterozygous dominant offspring has one dominant allele and one recessive allele while a homozygous recessive offspring has two recessive alleles.
For example, a cross between two parents that are heterozygous (Tt) for tall will produce one TT, two Tt and one tt. TT is homozygous dominant, Tt is heterozygous dominant and tt is homozygous recessive. An offspring with genotype tt has a two recessive alleles thus have a recessive-recessive genotype. Therefore the number of offsprings with recessive-recessive genotype is one.

Secondary succession
Explanation:
The type of succession in this forest is a secondary succession.
A secondary succession is from of succession that occurs in a place that lost it already established ecosystem.
It is succession in an area with soil already formed.
Primary succession is succession in a completely destroyed area that has lost its ecosystem components.
- This kind of succession occurs in an area that a wildfire ravages.
- The first set of plant to populate the area are usually short lived grasses.
- Then shrubs and more vegetation grows.
- With time, perennial forest trees surfaces and the forest is restored.
- Secondary succession is faster
