Some of the problems that can occur as a result of inbreeding include birth defects, decreased fertility, and increased susceptibility to disease. Inbreeding (also referred to as “consanguinity”) occurs when mates are related to each other due to incest, assortative mating, small population size, or population sub-structuring. Inbreeding leads to homozygosity which increases the chances of offspring being affected by genetic disorders or recessive traits. Inbreeding is unavoidable in small, isolated populations and can cause substantial fitness reductions compared to outbred populations. This form of self-incompatibility has been studied intensively in members of the mustard family ( Brassica ), including turnips, rape, cabbage, broccoli, and cauliflower.

Dear Student, Please find below the solution to the asked query: Advantage of inbreeding: preservation of good characteristics. In flowering plants, inbreeding may occur either within a single flower, known as autogamy (infrafloral selfing) or between flowers derived from one individual, known as geitonogamy. Even genetic conditions could be treated, and even cured, because of the work conducted by the. More recently, measurement of genetic. However, given a thorough population sampling, detailed genetic information, and known mother–offspring pairs, paternity can be inferred and accurate pedigrees from wild populations constructed ( Pemberton 2008 ). A very important further advantage of inbreeding is that it reduces the accumulation of recessive mutations in genomes. But inbreeding is unintentionally generated by keeping small populations for breeding and during selection. This review describes mating designs commonly used in plant breeding. Step 7: Add together the value for each path connecting the sire and dam of the individual in question. That encourages reproduction to occur so that the cycle of life can continue. .
