This question appears to be off-topic because it is about bricks not produced by biogenesis.

comment How does the creative process of Biological Evolution work?
The Blind Watchmaker would be a good book to read, probably better than The Selfish Gene. In any case, skip The Extended Phenotype until you are well acquainted with biology and evolution.

comment Dimensional analysis Question
Shigeta's equation should have used "hgb" instead of "rbc". To turn 1.7g hgb into rbc, you multiply it by the .3145 hgb/rbc value. Note the dimensional units work out.

comment Does recombination increase the additive genetic variance for fitness?
I don't think this response addresses the quote since this concerns crossing over. The quote says "bringing together favourable alleles from different chromosomes", which doesn't involve crossing over.

comment How does the brain know where a signal came from? What is the addressing system
If you perceive a sensation, it had a path; the signaling is indeed massively parallel. Some sensations are processed in the periphery and a derived signal sent on to the brain; The density also varies (the hands have many nerves, the back, few). There is also peripheral processing like the knee reflex. Also there are nerves that have little or no flow to the brain; see autonomic nervous system. If this answer is what you wanted, you can accept it by clicking the checkmark to the left.

comment PedigreeAnalysis Genetics
The G's seem mostly ok, but you don't know that Maria's grandmother is "GG". The A/a's are messed up; you're treating the disease allele as recessive, but it's dominant (XA). [but then I have no formal training; I've never had a genetics course or even college biology.]

ApothemCyte, the diagrams are concerned with both the autosomal disease and the X-linked disease; look at whether the person symbol is shaded on the left side or the right side.
