1.Given the percentage of DNA shared between two people, you can calculate their likely familial relationship.
We wrote a function, whatRelation(), that has one number parameter, percentSharedDNA, and returns the likely relationship. We expect the number passed in to always be an integer from 0 to 100, but for some reason it’s not working!
Here’s how it’s supposed to calculate the relationship:
100 should return 'You are likely identical twins.'
35-99 should return 'You are likely parent and child or full siblings.'
14-34 should return 'You are likely grandparent and grandchild, aunt/uncle and niece/nephew, or half siblings.'
6-13 should return 'You are likely 1st cousins.'
3-5 should return 'You are likely 2nd cousins.'
1-2 should return 'You are likely 3rd cousins.'
0 should return 'You are likely not related.'
Unfortunately, it’s not working how we want!
main.js
main.js
const whatRelation = percentSharedDNA => {
if (percentSharedDNA === 100) {
return 'You are likely identical twins.'
}
if (percentSharedDNA > 34) {
return 'You are likely parent and child or full siblings.'
}
if (percentSharedDNA < 13) {
return 'You are likely grandparent and grandchild, aunt/uncle and niece/nephew, or half siblings.'
}
if (percentSharedDNA > 5) {
return 'You are likely 1st cousins.'
}
if (percentSharedDNA > 2) {
return 'You are likely 2nd cousins.'
}
if (percentSharedDNA > 0) {
return 'You are likely 3rd cousins'
}
return 'You are likely not related.'
}
console.log(whatRelation(34))
// Should print 'You are likely grandparent and grandchild, aunt/uncle and niece/nephew, or half siblings.'
console.log(whatRelation(3))
// Should print 'You are likely 2nd cousins.'
