HARDY WEINBERG EQUILIBRIUM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A population that fulfils all of Hardy-Weinberg assumptions are said to be in ____
A
progression
B
evolution
C
imbalance
D
equilibrium
Explanation: 

Detailed explanation-1: -When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

Detailed explanation-2: -To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium. Example 1b: Recall: the previous generation had allele frequencies of = 0.6 and = 0.4.

Detailed explanation-3: -When a population meets all the Hardy-Weinberg conditions, it is said to be in Hardy-Weinberg equilibrium (HWE). Human populations do not meet all the conditions of HWE exactly, and their allele frequencies will change from one generation to the next, so the population evolves.
