never

One generation

Explanation:

If two populations are merged, each with different frequencies of one allele at one location, and random mating occurs immediately; after a generation this population will be in Hardy-Weinberg equilibrium, as there were no evolutionary processes within the population and mating occurred entirely at random.

The Hardy-Weinberg equilibrium states that in a population in which crossings occur at random and over which there are no evolutionary factors, gene and genotypic frequencies remain constant over the generations.

The importance of the Hardy-Weinberg Balance for natural populations lies in the fact that it establishes a model for gene behavior. Thus, it is possible to stimulate gene frequencies and genotypic frequencies over generations and compare them with those obtained in practice. If the observed values are significantly different from the expected values, it can be concluded that evolutionary factors are acting on this population and that it is evolving. If the values do not differ significantly, it can be concluded that the population is in equilibrium and therefore not evolving.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
