NEETBiologyEvolutionMCQ+4 / −1
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 kg or 4.5 to 5kg die. Which type of selection process is taking place?
  1. A
    Disruptive Selection
  2. B
    Cyclical Selection
  3. C

  4. D

View written solutionFree

Correct answer: D

It shows stabilizing selection as most of the newborn having average weight between 3 to 3.3 kg survive and babies with less and more weight have low survival rate. Stabilizing is a type of natural selection in which the population mean stabilizes on a particular nonextreme trait value.
