Outbreeding depression is a risk that sometimes limits the potential for genetic rescue or augmentations. Artificial pollination - definition. The concept is in contrast to inbreeding depression, although the two effects can occur simultaneously. Outbreeding Devices: ADVERTISEMENTS: Flowering plants have developed many devices to discourage self-pollination and to encourage cross-pollination. Self incompatibilty : It is a method used to prevent the germination of pollen grains on the stigma of the same flower to prevent self fertilisation .eg, tobacco,mustard and potato plant. Which is not true for outbreeding devices-A. The examples of outbreeding devices are: Unisexuality: The plant may be unisexual, which means it may exhibit either male or female gametes. Monson, Christopher A., and Kirsten C. Sadler. In biology, outbreeding depression is when crosses between two genetically distant groups or populations results in a reduction of fitness. This is the difference between inbreeding and outbreeding. Outbreeding, also called outcrossing, allogamy, or xenogamy, is the transfer of gametes from one individual to another, genetically different individual. What is the meaning of the term outbreeding devices of the flowers? Outbreeding devices are mechanisms which are followed and adapted by the plants in order to prevent self pollination. A. Outbreeding is performed between unrelated or distantly related individuals over several generations. Sometimes pollen is released before stigma is receptive. Outbreeding produces genetically diverse offspring that have a higher potential of adapting to new environments. C. Anther and stigma placed at different positions. 2. Outbreeding devices are mechanisms which are followed and adapted by the plants in order to prevent self pollination. The devices by which pollination will take place. D. Production of unisexual flowers. . Other articles where Outbreeding is discussed: inbreeding: …common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms. Artificial pollination is carried out from ancient times when people themselves used to transfer pollen grains from anthers to stigma. How are selective breeding techniques of hybridization and inbreeding opposite? Class-12CBSE Board - Outbreeding Devices and Pollen-Pistil Interaction - LearnNext offers animated video lessons with neatly explained examples, Study Material, FREE … Reference: 1. Inbreeding is useful in the retention of desirable characteristics or the elimination of undesirable ones, but it often results in decreased vigour, size, and fertility of the offspring because of the combined effect of harmful genes that… The general advantage of outbreeding is to promote an increase in phenotypic variability within a population. Continue self-fertilization does not come under the means of outbreeding devices… Some outbreeding devices used are :-1. The examples of outbreeding devices are: Unisexuality: The plant may be unisexual, which means it may exhibit either male or female gametes. Because the majority of flowering plants produce hermaphrodite flowers and are likely to come in contact with the stigma of the same flower. Continued self-fertilization. Best Answer. B.
