In a certain population of rabbits one year, 25 new rabbits are born and 5 move into the population from surrounding areas. Howe
sleet_krkn [62]

Answer:

Population change is 15

Explanation:

To calculate the change in populations, we add up the immigrants and births and the subtract the deaths and emigrant from it

Change in pop = (birth + immigrants) - (death + emigrants).

Where birth is 25, immigrants is 5, death is 10 and emigrants is 5.

Change in pop = (25+5) - (10+5)

= 30-15

Change in population is 15.

In the Hardy-Weinberg principle, the actual number values of p and q will not change if five specific conditions are being met.
JulsSmile [24]

In the Hardy-Weinberg principle, the values of p and q will not change if evolution is not occurring.

<h3>What is the Hardy-Weinberg principle?</h3>

The Hardy-Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies in a population.

The Hardy-Weinberg principle states that allele and genotypic frequencies remain constant in absence of evolutionary forces.

These evolutionary forces include nonrandom mating, gene drift, gene flow, mutation and natural selection.
