In certain portions of the Jewish population, there is a higher than normal
prevalence of a genetic disease called Tay Sachs disease, which is fatal to infants
within the first five years of life. This disease is caused by a recessive allele of a single
gene. Why does this disease persist, even though it is invariably fatal long before the
afflicted individual reaches reproductive age? (In other words, why doesn’t the
allele for Tay Sachs disease simply disappear?). (Note: this is a thinking question, no
Punnett squares needed, just answer the question) [
