The relative frequency of allele b (which represent the trait that affects oxygen content in the blood of Tibetan women) will increase in the population of Tibetan women over many generations.
Human adaptation on Tibetan plateau
- Tibet is a mountainous region in Asia.
- Tibetans have adapted to such environment and they have bigger blood vessels to carry more oxygen content compare to the people leaving in lower elevations.
Adaptive advantage in Tibetan women
- Tibetan women have two alleles.
- allele a and allele b which represents alternative versions of trait that affect oxygen content in the blood.
- Allele b confers the adaptive advantage because children born to mothers with the ab or bb genotype are more likely to survive infancy.
- The allele b will be passed to surviving offspring.
- Because offspring of ab and bb mothers are more likely to survive than aa and more than 50% will inherit a b allele, the frequency of the b allele among population will increase.
