Answer:
8 possible combinations
Explanation:
In a diploid organism (2n), there are two sets of chromosomes in each cell. Each set of chromosome is contributed by each parent i.e one set of chromosome from the father and one set from the mother.
To determine the number of possible combinations in each gamete of a cell, we use the formula 2^n, where n = number of chromosomes in haploid gametes. In this case, the cell contains 3 pairs of chromosomes, meaning that each gamete will have 3 chromosomes. However, there will be 2³ = 8 possible combinations of chromosomes in each gametes.
Answer:
There are four steps in secondary Succession.

Because they are from different geographical location does not mean they won't mate and produce fertile offsprings.
