Question

Define sexual reproduction define two methods of assexual reproduction in anmals class 8

Answer 1

Answer:

1. Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).
2. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

• Fission is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original.
• Budding a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism.
• Fragmentation, the splitting of cells into two parts and makes new bodies is known as fragmentation. Each fragment develops into a mature clone genetically and morphologically identical to its parent. It is a type of asexual reproduction or vegetative propagation.

Answer 2

Answer:

Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce an organism composed of cells with two sets of chromosomes (diploid)...

Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
