Sexual Reproduction – Gametes and Fertilization

Individual organisms come and go, but, to a certain extent, organisms transcend time through producing offspring. Reproduction in animals occurs in two primary ways, through sexual reproduction and through asexual reproduction.While most animal organisms reproduce by sexual means, some are also capable of reproducing asexually. In sexual reproduction, two individuals produce offspring that inheritgenetic characteristics from both parents.

Female And Male Gamete Cells: Called Sex Cells | Science …

Gamete cells, also known as sex cells, are the cells responsible for sexual reproduction. A male gamete is called sperm (spermatozoa) and is a haploid cell formed throughSpermatogenesis. A female gamete is called an ova or egg cells (Oocytes), which are haploid cells carrying one copy of each chromosome.

Hermaphrodite – Wikipedia

In biology, a hermaphrodite is an organism that has reproductive organs normally associated with both male and female sexes.[1] Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes.[2] In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the "female" or "male". For example, the great majority of tunicates, pulmonate snails, opisthobranch snails and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates

Penis – Wikipedia

A penis (plural penises or penes ) is the primary sexual organ that male and hermaphrodite animals use to inseminate sexually receptive mates (usually females and hermaphrodites respectively) during copulation.[1] Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penes in the various species are not necessarily homologous. For example, the penis of a mammal is at most analogous to the penis of a male insect or barnacle.[citation needed] The term penis applies to many intromittent organs, but not to all; for example the intromittent organ of most cephalopoda is the hectocotylus, a specialised arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as hemipenes

Dolphin – Wikipedia

Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins)

Male – Wikipedia

A male () organism is the physiological sex that produces sperm. Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization. A male cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually.
