What reproduction has no formation of gametes?

Is gamete formation occur in asexual reproduction?

Asexual Reproduction: When a single parent participates in reproduction, and gamete formation does not take place; it is called asexual reproduction. … In some examples of sexual reproduction, a single parent may produce both the male and female gametes and participate in reproduction.

What type of reproduction does not use gametes in producing offspring?

Meiosis is not directly involved in the production of gametes because the organism that produces the gametes is already a haploid. Fertilization between the gametes forms a diploid zygote.

What animal gets pregnant by itself?

Most animals that procreate through parthenogenesis are small invertebrates such as bees, wasps, ants, and aphids, which can alternate between sexual and asexual reproduction. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish or lizards.

Where are gametes formed?

Gametes (germ cells) are produced in the gonads. In females, this is called oogenesis and, in males, spermatogenesis.

How are female gametes produced?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
