Answer:
The correct answer would be Gene pool for the population.
A gene pool is defined as the sum total of all the genes present in an inter-breeding population at a specific time.
It includes all the alleles of all the loci within the genes of a interbreeding population or species.
The composition of the gene pool of a population can change with course of a time due to evolution.
A large and diverse gene pool enhances the ability of a population to adapt, survive and evolve in a nature.
The biodiversity in the rain forest has economic value, like large abundance of materials Available for usage, the ecological values like the oxygen created by the rainforest are great too, for they allow us to breath, and the aesthetic of the forest provides and excellent scenery for photography and touring.
Answer:
The correct answer would be meiosis.
In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.
It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.
The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.
Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.
In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.
