haploid

I have no idea why haploid's comment went dead - he raises a very good point.

A complete haploid human genome is 3 billion base pairs.

That must be what the "H" stands for, and I, for one, would attempt not to treat anyone differently just because they happened to be haploid.

And our gonads are the haploid gametophyte phase, which trigger development of sex organs.

Pollen is a bit like a spore in that it's tiny and contains haploid genes, but still I'm guessing that process of reproduction is considerably more durable to increased UV.

Only a fraction of that carries functional information, however, so the upper KC value may be quite a bit lower than that].That must be 3 x 10^9 base pairs, in the haploid genome.

This feels very much like a prototypical version of sex with two 'haploid' cells merging to form a 'diploid'.It's not quite clear from the article what happens to these merged cells in the long-run.

My understanding was that it's evolutionarily advantageous for eusocial insects to cooperate at least in part because they're haploid.

Nevertheless, the mitochondrial genome and the Y chromosome each represents only a single haploid locus and is more susceptible to large stochastic variation, bottlenecks, and selective sweeps.
