Which one of the following factors will not affect the Hardy-Weinberg equilibrium? [2024]
Genetic recombination
Genetic drift
Gene migration
Constant gene pool
(4)
Five factors are known to affect Hardy-Weinberg equilibrium. These are gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection.
Natural selection where more individual acquire specific character value other than the mean character value, leads to [2022]

In a species, the weight of newborn ranges from 2 to 5 kg. 97% of the newborn with an average weight between 3 to 3.3 kg survive whereas 99% of the infants born with weights from 2 to 2.5 or 4.5 to 5 kg die. Which type of selection process is taking place? [2019]
Cyclical selection
Directional selection
Stabilising selection
Disruptive selection
(3)
Stabilising selection is a balancing type of natural selection which favours average sized individuals and eliminates extreme individuals.
