Two major types of sexual reproduction aresyngamyandconjugation.(1) Syngamyrefers to the fusion of haploid sex cells resulting in the formation of a diploid zygote. Thus, in essence, syngamy refers tofertilization. It is the most common type of reproduction in multicellular sexual populations, incl...
SEXUAL REPRODUCTION CONCEPT Sexual reproduction is one of the two major ways, along with asexual reproduction, that plants and animals create offspring and thus propagate the species. Critical to sexual reproduction is the process of fertilization, whereby the male and female sex cells fuse, or ...

(OCRs) might provide information on the regulatory status of the cells. To identify OCRs, we used the ImmGen dataset of Assay for Transposase-Accessible Chromatin (ATAC-seq) data38that profiled many immune cell types. For three cell types, namely, B, MF, and T4 cells, both male and ...
Miracidia develop into sporocysts within the snails, which then produce daughter sporocysts through asexual reproduction, eventually giving rise to cercariae. The cercariae are released into the water and penetrate the skin of human hosts. After infection, cercariae transform into schistosomula and ...
