  2. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.

  3. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    Organisms that reproduce sexually yield a smaller number of offspring, but the large amount of variation in their genes makes them less susceptible to disease. Many organisms can reproduce sexually as well as asexually. Aphids, slime molds, sea anemones, some species of starfish (by fragmentation), and many plants are examples. When ...

  4. Plant reproductive morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_reproductive_morphology

    The sporophyte of a flowering plant is often described using sexual terms (e.g. "female" or "male") based on the sexuality of the gametophyte it gives rise to. For example, a sporophyte that produces spores that give rise only to male gametophytes may be described as "male", even though the sporophyte itself is asexual, producing only spores.

  5. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts.

  6. Polyploidy - Wikipedia

    en.wikipedia.org/wiki/Polyploidy

    Two examples of natural autopolyploids are the piggyback plant, Tolmiea menzisii [19] and the white sturgeon, Acipenser transmontanum. [20] Most instances of autopolyploidy result from the fusion of unreduced (2n) gametes, which results in either triploid (n + 2n = 3n) or tetraploid (2n + 2n = 4n) offspring. [21]

  7. Punnett square - Wikipedia

    en.wikipedia.org/wiki/Punnett_square

    The following example illustrates a dihybrid cross between two double-heterozygote pea plants. R represents the dominant allele for shape (round), while r represents the recessive allele (wrinkled). A represents the dominant allele for color (yellow), while a represents the recessive allele (green).

  8. Dihybrid cross - Wikipedia

    en.wikipedia.org/wiki/Dihybrid_cross

    In the example pictured to the right, RRYY/rryy parents result in F 1 offspring that are heterozygous for both R and Y (RrYy). [4] This is a dihybrid cross of two heterozygous parents. The traits observed in this cross are the same traits that Mendel was observing for his experiments. This cross results in the expected phenotypic ratio of 9:3:3:1.

  9. Asexual reproduction - Wikipedia

    en.wikipedia.org/wiki/Asexual_reproduction

    Examples of vegetative reproduction include the formation of miniaturized plants called plantlets on specialized leaves, for example in kalanchoe (Bryophyllum daigremontianum) and many produce new plants from rhizomes or stolon (for example in strawberry). Some plants reproduce by forming bulbs or tubers, for example tulip bulbs and Dahlia ...
