Some unicellular organisms undergo some for of sexual something like reproduction. Diploid cells undergo a division into four haploid cells in a process very similar to meiosis. Haploid cell fuse in a process somewhat similar to conception. read more
Some unicellular organisms undergo some for of sexual something like reproduction. Diploid cells undergo a division into four haploid cells in a process very similar to meiosis. Haploid cell fuse in a process somewhat similar to conception. Whether the entire cycle can be called reproduction is a matter of semantics. read more
Yeast has two modes of reproduction. Under normal conditions, it just divides. But stress causes it to form spores which are gametes with a haploid set of DNA, of a single gender. read more
The union of these two distinct processes, sex and reproduction, into sexual reproduction is seen in unicellular eukaryotes. Figure 2.8 shows the life cycle of Chlamydomonas. This organism is usually haploid, having just one copy of each chromosome (like a mammalian gamete). read more
