Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
If undisturbed by other forces, random sexual reproduction among members of a large population in nature leads to
|
|
changes in gene frequencies
|
|
|
generations of unchanged gene frequencies
|
|
|
new traits
|
|
|
a change in the frequencies of 2pq, but not p2 or q2
|
Explanation:
Detailed explanation-1: -According to Hardy-Weinberg principle, allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
Detailed explanation-2: -Because the allele frequencies, then hardy Weinberg population shifted over time means that external evolutionary pressure is acting on a population.
Detailed explanation-3: -So, the correct answer is ‘Random mating’
Detailed explanation-4: -Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population, the population violates the Hardy-Weinberg assumptions, and evolution occurs.
