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… 2. In biology, outbreeding depression is when crosses between two genetically distant groups or populations results in a reduction of fitness. The devices by which pollination will take place. Outbreeding depression is a risk that sometimes limits the potential for genetic rescue or augmentations. Outbreeding devices are mechanisms which are followed and adapted by the plants in order to prevent self pollination. Because the majority of flowering plants produce hermaphrodite flowers and are likely to come in contact with the stigma of the same flower. The examples of outbreeding devices are: Unisexuality: The plant may be unisexual, which means it may exhibit either male or female gametes. The general advantage of outbreeding is to promote an increase in phenotypic variability within a population. Monson, Christopher A., and Kirsten C. Sadler. 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. How are selective breeding techniques of hybridization and inbreeding opposite? Artificial pollination - definition. This is the difference between inbreeding and outbreeding. Outbreeding devices are mechanisms which are followed and adapted by the plants in order to prevent self pollination. The concept is in contrast to inbreeding depression, although the two effects can occur simultaneously. Continue self-fertilization does not come under the means of outbreeding devices… Class-12CBSE Board - Outbreeding Devices and Pollen-Pistil Interaction - LearnNext offers animated video lessons with neatly explained examples, Study Material, FREE … C. Anther and stigma placed at different positions. D. Production of unisexual flowers. Artificial pollination is carried out from ancient times when people themselves used to transfer pollen grains from anthers to stigma. Other articles where Outbreeding is discussed: inbreeding: …common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms. Sometimes pollen is released before stigma is receptive. Continued self-fertilization. Outbreeding, also called outcrossing, allogamy, or xenogamy, is the transfer of gametes from one individual to another, genetically different individual. Some outbreeding devices used are :-1. Reference: 1. What is the meaning of the term outbreeding devices of the flowers? Best Answer. 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.
