What are some examples of asexually reproduction in a many celled organism?

Answer 1

budding, binary fission, and fragmentation are the three most common ways to asexually reproduce.

Binary fission is most common in unicellular organisms like bacteria. Budding and fragmentation are most common in multicellular organisms. Examples of organism that buds is the Hydrozoa and an example of organism which fragments to reproduce is sponges (Porifera).

There are several different types of asexual reproduction. These include:

1. Binary Fission
2. Budding
3. Spore formation
4. Just added from my text book Regeneration

Binary fission is where an organism splits itself more or less in half. Each then grows to a new fully matured organism. Some worms reproduce in this way.

Budding is where a small part of the parental organism is separated from the parent. This small part then grows into a fully formed adult.

Spore formation is where spores are formed in the parental generation. These spores essentially act as seeds, except that they are genetic clones of their parents. These spores then grow into full sized organisms. Fungi reproduce this way.

Answer 2

There are examples of parthenogenesis in the hammerhead shark and the blacktip shark.In both cases, the sharks had reached sexual maturity in captivity in the absence of males, and in both cases the offspring were shown to be genetically identical to the mothers.

Reptiles use the ZW sex-determination system, which produces either males (with ZZ sex chromosomes) or females (with ZW or WW sex chromosomes).

Polyembryony is a widespread form of asexual reproduction in animals, whereby the fertilized egg or a later stage of embryonic development splits to form genetically identical clones. Within animals, this phenomenon has been best studied in the parasitic Hymenoptera. In the 9-banded armadillos, this process is obligatory and usually gives rise to genetically identical quadruplets. In other mammals, monozygotic twinning has no apparent genetic basis, though its occurrence is common. There are at least 10 million identical human twins and triplets in the world today.

Bdelloid rotifers reproduce exclusively asexually, and all individuals in the class Bdelloidea are females. Asexuality evolved in these animals millions of years ago and has persisted since. There is evidence to suggest that asexual reproduction has allowed the animals to evolve new proteins through the Meselson effect that have allowed them to survive better in periods of dehydration.[17]

Molecular evidence strongly suggest that at least two species of the stick insect genus Timema have used only asexual (parthenogenetic) reproduction for one million years, the longest period known for any insect.

Answer 3

1) Budding- Hydra, a freshwater animal, can reproduce asexually by budding. The bud is a small exact copy of the adult.

2) Regeneration- Certain worms can be cut to form two separate worms.

Answer 4

Hydra,Planaria and many worms of phyllum Platehelmenthis,

Answer 5

Sea stars, sea anemones, sponges, planarians, and echinoderms. Other organism not necessarily things that we would think to be alive are plants. Plants also reproduce asexually.

Answer 6

earthworms.

Answer 7

Worms

Answer 8

poinsettias
