I just learned that dogs have 78 chromosomes, compared to our 46. And then I saw that chimps also have a couple more chromosomes than us as well. Do they have more genetic information than us? Can dogs or chimps’s bodies do things (metabolically) that we can’t do? And how does this increase or decrease of chromosomes occur? The few medical conditions where humans have extra chromosomes tend to not be beneficial, why is that?
In: Biology
Two chromosomes fused together, specifically chromosome 2 in humans. Chromosomes have end markers called telomeres, specific sequences of DNA nucleotides. In humans there was a mutation that caused the telomeres to no longer encode properly, fusing the chromosomes together. There is still a set of ‘almost telomere’ markers in the middle.
