This confuses me. I find it highly unlikely the average human shares more genes with a chimpanzee than another human and even more unlikely that siblings only share 50% of their genes.
probability estimates (statement is true):
99% genetic similarity to a chimpanzee = 75%
95% genetic similarity to a random human = a low nonzero number
50% genetic similarity to a sibling = 0%
95% genetic similarity to a random human given 99% genetic similarity to a chimp = 0%
I am going to research this.
EDIT: findings:
Researching an an actual number is exceeding difficult. About 50% of the pages are non-secular websites (this may be my non-optimized google searching). The rest are a mix between technical articles and articles formatted for the average human (average being living in a English speaking and developed nations).
99% genetic similarity to a chimpanzee
Mostly correct. Estimates range between 95%^[1] and 98.8%^[2]
95% genetic similarity to a random human
Incorrect. Estimates are at 0.1%^[1]. I did not notice other numbers.
50% genetic similarity to a sibling
Incorrect as you stated it (comparing total gene dissimilarity). You might want to reword it since you were probably comparing what percentage of gene can be attributed to a parent.
This confuses me. I find it highly unlikely the average human shares more genes with a chimpanzee than another human and even more unlikely that siblings only share 50% of their genes.
It puzzles me as well. I believe the answer is that there are multiple concepts of “shared genes”, but I have never been clear what they are.
