Sexual Reproduction
Sexual reproduction is another breeding diversity, as well as bringing in a new living fruit for a very short period of time. In contrast to sexual reproduction, there are two different living organisms in sexual reproduction. During sexual reproduction, a new organism will form by combining genetic material between these creatures.
The Processes of Sexual Production Process
1 - Meiosis Section: The phenomenon that occurs in the meiosis division is the number of existing chromosomes falling from the present state. During this division, each pair of chromosomes changes parts among themselves. During the meiosis process, the first process of sexual reproduction, the number of chromosomes reaches another number (n) of diploid numbers (2n). This means that the number of chromosomes can be reduced by half. At the next fertilization step, haploid gametes reunite to form a diploid zygote and reach the first (2n) number of chromosomes.
2- Crossing Method: This is the method of changing chromosome parts that they perform between themselves. The living organisms that change parts between chromosomes by the crossing method obtain homologous recombination by this method.
Sexual reproduction and its first examples
There is a wide variety of debates about where and how sexual prophets first appeared, just as evolution is generally murdered. The evolution of sexual breeders is partly unknown. The research is J.J. Buttefiel wrote in 2000 (Paleobiology Bangiomorpha pubescens n. Gen., N. Sp., Inferences for sex evolution, Mesoproterozoic / Neoproterozoic radiation of multicellular and eukaryotes.) 26 pp. 386-404. The fossils of living things proliferated by the first sexual reproduction show that Strana belongs to the bearer who lived 1 to 1.2 billion years ago.
Races Survived by Sexual Reproduction
In general, almost all animals and plants appear to reproduce, even for the vast majority of large-scale macroscopic organisms. We will then provide information on how the creatures have gone through sexual reproduction. But there is something to consider here.
Bacterial Conjugation is known as the cell-based way of transferring genetic material between two bacteria, ie the transfer of DNA should not be confused with the type of sexual reproduction. Although this is related to the transfer of DNA, such reproduction is not a form of sexual reproduction.
