AI Thread Summary
The discussion clarifies the concept of the human genome, emphasizing that it encompasses the complete set of human genes rather than merely the total amount of DNA in a diploid cell. The mention of approximately 20,000 genes refers to specific segments of chromosomes located at distinct loci, rather than a direct measurement of DNA quantity. Additionally, the term "extremely heterogeneous" highlights the genetic diversity within the human genome, indicating significant variation among individuals.

Hello everyone,

Ok I read the definitions but I'm confused. What I'm thinking is genome, is the amount of DNA in one diploid cell. So when they say we have 20 000 genes in our body, are they referring amount of DNA in one diploid cell. Also what do they mean when they say human genome is extremely heterogenous. Thank you :smile:

human genome refers to the entire collection of human genes
the 20000 genes does not refer to the amount of DNA...genes are specified by segments of a chromosome at a loci

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
