And do bacterias have genders.
I have to correct myself here. I was wrong, apparently one of the dividing lines between prokaryotes (bacteria) and eukaryotes (basically everything else) is that bacteria does not sexually reproduce, so I was wrong. So to answer your question, no, bacteria doesn't have genders. How every, there are microscopic multi-cellular protista that do.
"Sexual reproduction is the primary method of reproduction for the vast majority of macroscopic organisms, including almost all
eukaryotes (which includes
animals and
plants).
[1]Prokaryotes reproduce through
asexual reproduction but may display processes similar to sexual reproduction (mechanisms for
lateral gene transfer such as
bacterial conjugation,
transformation and
transduction), but they do not lead to reproduction."
And
"The first
fossilized evidence of sexual reproduction in eukaryotes is from the
Stenian period, about 1 to 1.2 billion years ago."
Also:
""Multicellular filaments from the ca. 1200-Ma Hunting Formation (Somerset Island, arctic Canada) are identified as bangiacean red algae on the basis of diagnostic cell-division patterns. As the oldest taxonomically resolved eukaryote on record
Bangiomorpha pubescens n. gen. n. sp. provides a key datum point for constraining protistan phylogeny. Combined with an increasingly resolved record of other Proterozoic eukaryotes, these fossils mark the onset of a major protistan radiation near the Mesoproterozoic/Neoproterozoic boundary.
Differential spore/gamete formation shows
Bangiomorpha pubescens to have been sexually reproducing, the oldest reported occurrence in the fossil record. Sex was critical for the subsequent success of eukaryotes, not so much for the advantages of genetic recombination, but because it allowed for complex multicellularity. The selective advantages of complex multicellularity are considered sufficient for it to have arisen immediately following the appearance of sexual reproduction. As such, the most reliable proxy for the first appearance of sex will be the first stratigraphic occurrence of complex multicellularity."
