Barring transcription errors and mutations you are a subset of your ancestors genes.
Are those things that one can reasonably ignore? If they aren't significant where does genetic complexity come from?
Complexity arises in a lot of ways.
You've got several billion base pairs of genes, organized into roughly 20-25,000 gene loci that do something. Each loci can have a wide variety of expressions depending on how it's encoded. And some loci can affect the expression of other loci, too.
So there are a LOT of coins being tossed in the generation of one particular gene, or set of genes to produce a unique organism.
And those are mixed and matched through random breeding, meiosis, etc. etc. The likelihood of even two eggs from the same mother having the exact same genetic content is really, really, small.
Appreciate your two responses. I was going to quibble a bit but harassing you into posting a genetics text seemed too cruel. However, just to be clear I wasn't asking about complexity in terms of permutations inside a genome that result in varied expression; I was asking about how we got from ancestral organisms with relatively small genomes to the larger genomes of clever apes that waste time on internet discussion boards if the genome only goes through the process of sub-setting.
^^^ Imperfect, sure. A racket, no. US Masters helps a lot of clubs access pools that would otherwise be closed to them because of liability insurance requirements. IIRC, most Masters swimmers don't go to meets but they do benefit from the insurance cover. Typically, the open water swim races around here are organized by private clubs but that may change. The amount of coverage that the local government is requiring and the cost of that cover are increasing. I am aware of one local open water race canceled this year because the insurance required by the government was no longer affordable by the club. Grouping together for purchasing or advocacy makes sense and provides value.
