What is a bisexual reproduction?

Bisexual reproduction is the production of offspring formed by the union of gametes from two genetically different parents (Figures 7-1C and D, and 7-2). An exception to this is found in individual animals that have both male and female reproductive organs, a condition which is called monoecious (Gr.

What term refers to the fusion of gametes that occurs inside the body of the female or hermaphrodite?

cross-fertilization, also called Allogamy, the fusion of male and female gametes (sex cells) from different individuals of the same species. Moreover, many of the hermaphroditic species that are capable of self-fertilization (q.v.) also have capabilities for cross-fertilization.

Is one parent a sexual reproduction?

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.

What type of reproduction involves the fusion of male and female gametes?

Sexual reproduction
Sexual reproduction is a mode of reproduction involving the fusion of haploid female and male gametes. The fusion of these gametes occurs at fertilization resulting in the formation of a diploid zygote.

What are gametes?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These cells develop into sperm or ova.

What are bisexual organisms?

When both male and female reproductive system are present within the same organism such organisms are called bisexual organisms or hermaphrodites. For example : earthworm, leech, starfish etc.

What do you mean by parthenogenesis give an example?

It is a method in which a new individual developed without fertilization. Here, males do not have any role to play and only female gametes develop into new offspring. Examples of plants showing parthenogenesis include honey bees, ants, birds.

How many parent’s is are involved in sexual reproduction?

two parents
Sexual reproduction requires two parents. Each parent contributes a gamete – a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

Are gametes produced by asexual reproduction?

During asexual reproduction in plants, gametes are not formed. Plant cells carry information that can be used to create other plants via asexual reproduction. Plants can regenerate entire plants that are identical to the parent.

What is the fusion of gametes called?

During the process of fertilization, a series of reactions triggers the fusion of gametes to produce a diploid cell called a zygote.

Where does the fusion of male and female gametes take place?

the fallopian tube
Fertilization is the natural life process, which is carried out by the fusion of both male and female gametes, which results in the formation of a zygote. In humans, the process of fertilization takes place in the fallopian tube.

What is gamete fusion?

“Fusion of gametes” means the fusion of the nucleus of male gamete (sperm) with the nucleus of the feminine gamete (egg). This process is additionally referred to as fertilization.

Does asexual reproduction involve fusion of gametes?

Asexual reproduction does not involve the fusion of gametes, and therefore, the offsprings produced are genetically identical to the parent. The organisms produced by asexual reproduction are less diverse in nature. This type of reproduction is practised widely by unicellular organisms.

What is sexual reproduction in biology?

Sexual Reproduction. “Sexual reproduction is a type of reproduction that involves the production of an offspring by the fusion of male and female gametes.”. In sexual reproduction, male and female gametes are formed to produce an offspring. These gametes are either formed by the same individual or by different individuals of the opposite sex.

How do animals reproduce sexually and asexually?

Reproduction in Animals. Animals reproduce sexually as well as asexually. Sexual reproduction involves the fusion of male and female gametes. This process is known as fertilization. Fertilization can be external or internal. External fertilization is the process in which the male sperm fertilizes the female egg outside the female’s body.

What is the source of variation in asexual reproduction?

A likely explanation is that the variation that sexual reproduction creates among offspring is very important to the survival and reproduction of those offspring. The only source of variation in asexual organisms is mutation.
