A species with a diploid number of 26, so 26= 2n ( a diploid cell),
so in haploid condition, chromosome number becomes half (13 in this case). triplod is when 2n + n, and 2n +2n ( tetploid). Trisomy and monosomy is the addition or deletion of a sinlge chromosome of a sinlge set .
Haploid=13, one chromosome from each pair of chromosome set,
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.
The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
