PYQ NEET- Genetics And Evolution Concepts 1 L-8
Question: In a species, the weight of a newborn ranges from 2 to 5 kg. 97% of the newborns 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 kg to 5 kg die. Which type of selection process is taking place? NEET-2019
A) Cyclical selection is a term used in evolutionary biology to describe a process where certain traits or genetic variations are repeatedly selected for over time, often due to environmental changes or shifts in selective pressures.
B) Directional selection
C) Stabilizing selection
D) Disruptive selection is a type of natural selection where extreme phenotypes are favored over intermediate ones, leading to increased genetic diversity within a population.
