Question
Classify the following examples based on what type of natural selection they describe. 15 A new flu vaccine is needed every year because the lu vius evolves resistance to our immune syslem cells crealed by the old vaocine Very large and very small newboms are more likely to Chloroquine is no longer ellective against malaria because it has evolved suffer serious health problems resistance against it Bird clutch sizes consisting of 4-5 eggs are more likely to hatch than larger or smaller clutches One population of finches very different phenotypesoccupy different niches and eventually evolve to have British land snails comprise two as they are both adapted to different habitats different beak sizes Directional Selection Disruptive Selection Stabilizing Selection ?PreyExplanation / Answer
Ans: Directional Selection:
1 British land snails comprise two very different phenotypes as they are both adopted different habitats.
2 One population of finches occupy different niches and eventually evolve to have different beak size.
Disruptive Selection:
1 A new flu vaccine is needed every year because the flu virus evolves resistance to our immune system cells created by the old vaccine.
2 Choroquine is no loger effective against malaria because it has evolved resistance agaist it
Stabilizing Selection:
1 Very large and very small newborns are more likely to suffer serious health problems.
2 Bird Clutch size consisting of 4-5 eggs are more likely to hatch than larger or smaller clutches.
