Question

which fertilization in phylum chordata​

Answer 1

Explanation:

reproduction among members of this phylum is sexual, meaning that an egg is fertilized by a sperm. There are a few animals in this group that reproduce asexually, ''a'' meaning ''without sex.'' For example, some tunicates (those pouch-like organisms) reproduce by budding off a part of themselves, and that bud, which is genetically identical to the parent, develops into a new individual. Additionally, some fish and reptiles reproduce through parthenogenesis. This is a form of asexual reproduction in which an embryo develops without being fertilized.

Also, most chordates are dioecious, meaning that the males and females of species are different (''di'' for ''two''). For example, humans and other mammals, most fish, birds, and reptiles, etc., have males and females that have distinctly different reproductive organs. But some chordates are hermaphroditic, meaning that they have both male and female reproductive structures.
