  2. Asexual reproduction - Wikipedia

    en.wikipedia.org/wiki/Asexual_reproduction

    Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...

  3. Gynogenesis - Wikipedia

    en.wikipedia.org/wiki/Gynogenesis

    Gynogenesis is a disadvantageous mating system for males, as they are unable to pass on their DNA. The question as to why this reproductive mode exists, given that it appears to combine the disadvantages of both asexual and sexual reproduction, remains unsolved in the field of evolutionary biology.

  4. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    This form of asexual reproduction is thought in some cases to be a serious threat to biodiversity for the subsequent lack of gene variation and potentially decreased fitness of the offspring. [ 39 ] Some invertebrate species that feature (partial) sexual reproduction in their native range are found to reproduce solely by parthenogenesis in ...

  5. Heredity - Wikipedia

    en.wikipedia.org/wiki/Heredity

    Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

  6. Parthenogenesis in squamates - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis_in_squamates

    Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards). [1]

  7. Androgenesis - Wikipedia

    en.wikipedia.org/wiki/Androgenesis

    Androgenesis is a system of asexual reproduction that requires the presence of eggs and occurs when a zygote is produced with only paternal nuclear genes.During standard sexual reproduction, one female parent and one male parent each produce haploid gametes (such as a sperm or egg cell, each containing only a single set of chromosomes), which recombine to create offspring with genetic material ...

  8. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. [1] Vegetative reproduction involves a vegetative piece of the original plant producing new individuals by budding, tillering , etc. and is distinguished from apomixis , which is a replacement of sexual reproduction, and in some cases ...

  9. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce [ 1 ] and organisms only pass on 50% of their genes .
