<h3>What was conclusion of Edward jenner in case of small pox?</h3>

He also came to the conclusion that small pox may be passed from one person to the next. Edward Jenner came to this conclusion based on stories he had heard about dairy maids being immune to smallpox.

In 1736, Edward Jenner met Sarah Nelms, a young dairy girl with small pox lesions. Edward Jenner then vaccinated an 8-year-old kid named James Phipps with material from Nelms' small pox lesion. James Phipps suffered a fever and became unwell, but he recovered completely after ten days.

Jenner infected the same boy with materials from a fresh small pox lesion a month later. There was no sickness in the boy.

  • Homozygosity is the presence of two dominant alleles (AA) or two recessive alleles (aa).
  • The recessive allele is suppressed by the dominant one.

Heterozygous dominant:

  • The two distinct alleles in a heterozygous genotype interact with one another. This controls how their characteristics are shown.
  • This encounter frequently centers on dominance.
  • The stronger allele is referred to as "dominant," whilst the weaker allele is referred to as "recessive." The dominant allele covers up this recessive one.
