diverse mating and reproductive strategies most often resulting in the male depositing spermatophore
within the female, which stores the sperm until she is ready for egg fertilization. After fertilization, and the
formation of a zygote, and varying degrees of development; they develop further within the female and
live born offspring are produced, tiny juvenile fish of which the sex isn't vissible yet. The number of
males/females within the offspring are due to the aquaenvironment' temperature.
Below 23-24 degrees more females, above 24-25 degrees more males!
Sexual dimorphism is the systematic difference in form between individuals of different sex in the same
species. Examples include colour (specifically referred to as sexual dichromatism), size, and the presence
or absence of parts of the body used in courtship displays or fights, such as ornamental feathers, horns,
antlers, or tusks.
In the case of members of the subgenera; Acanthophacelus and Micropoecilia, the differences lie on the
body, black (horizontal-line/vertical-bar) markings, (metalic) collor markings, colloured fins, total body
collouring, long and thin body and a gonopodium are part of the male. Larger and more robust body, (No
marking and collouration as in male-part) "blanco" body but a yet light metalic or black collouration
covering the body and gonopodore are part of the female.
Altough in hobby-breeders and pro-breeding facilities females appear with full fin-collorations, and light
body markings, but that's part of unnatural-selection, and domestication.
What is sexual reproduction?
Sexual reproduction is the creation of a new organism by combining the genetic material of two
organisms. The two main processes are: meiosis, involving the halving of the number of chromosomes;
and fertilization, involving the fusion of two gametes and the restoration of the original number of
chromosomes. During meiosis, the chromosomes of each pair usually cross over to achieve homologous
recombination.
The evolution of sexual reproduction is a major puzzle. The first fossilized evidence of sexually
reproducing organisms is from eukaryotes of the Stenian period, about 1 to 1.2 billion years ago. Sexual
reproduction is the primary method of reproduction for the vast majority of macroscopic organisms,
including almost all animals and plants. Bacterial conjugation, the transfer of DNA between two bacteria,
is often mistakenly confused with sexual reproduction, because the mechanics are similar.
A major question is why sexual reproduction persists when parthenogenesis appears in some ways to be
a superior form of reproduction. Contemporary evolutionary thought proposes some explanations. It may
be due to selection pressure on the clade itself�the ability for a population to radiate more rapidly in
response to a changing environment through sexual recombination than parthenogenesis allows.
Alternatively, sexual reproduction may allow for the "ratcheting" of evolutionary speed as one clade
competes with another for a limited resource.
