Which assumption must be correct for a population to be in hardy-weinberg equilibrium for a specific gene? see section 23.1 ( page 458) ?

There are five basic Hardy-Weinberg assumptions:

1. Random Mating -

2. No natural selection - all members of the parental generation survived and contributed equal numbers of gametes to the gene pool, no matter the genotype

3. No genetic drift (random allele frequency changes) - the population is infinitely large.

4. No gene flow - no new alleles were added by immigration or lost through emigration (no migration)

5. No mutation -  There must be mutation equilibrium.

No genetic drift can affect allele frequencies for the gene.

Explanation:

Any condition that changes allele frequencies in the population represents a violation of the Hardy-Weinberg principle and means that the population will not be in Hardy-Weinberg equilibrium.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
