Oral polio vaccine is highly effective and inexpensive (about US$0.10 per dose, or US$0.30 per child and its availability has bolstered efforts to eradicate polio. A study carried out in an isolated Eskimo village showed that antibodies produced from subclinical wild virus infection persisted for at least 40 years. Because the immune response to oral polio vaccine is very similar to natural polio infection, it is expected that oral polio vaccination provides similar lifelong immunity to the virus.
Contact immunity to polio can occur when attenuated poliovirus derived from the oral polio vaccine is excreted, and infects and indirectly vaccinates unvaccinated individuals.
Answer:
1:1 (brown:blonde)
Explanation:
Brown hair color (B) is dominant over blonde hair color (b).
Heterozygous parent will have the genotype Bb
Homozygous recessive parent will have the genotype bb.
Crossing hetezygous parent with homozygous recessive parent:
Bb x bb
Progeny: Bb, Bb, bb, and bb.
2 Bb brown hair
2 bb blonde hair
Phenotypic ratio = 1:1 (brown:blonde)
The correct answer is 1:1 (brown:blonde).
