Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Changes in the structure of a chromosome, One or more chromosomes of a normal set are, Due to meiotic nondisjunction - members of pairs, POLYPLOIDY - the duplication of chromosome sets, There are 2 types of polyploidy autopolyploidy, The multiplication of chromosomes sets within a, For example, a failure of meiosis during gamete, The tetraploids formed can mate with themselves, It refers to the contribution of two different, It begins with 2 different species interbreeding, Interspecific hybrids are usually sterile, During the history of the clone, a mitotic error, The hybrid will be able to make gametes because, The union of gametes from this hybrid may give, Most mutations are either neutral or deleterious, There are only approximately 1 X 10-5 mutations, Assume that there are at least 100,000 pairs of, The average number of mutations arising per, There are about 6 X 109 humans in the world with, Clearly, the number of mutations in a population, Even if only a very small fraction of these were, The probability of a mutation is not random with, Also, the mutation rates for organisms can be, Mutations are, however, random with respect to, There appears to be no evidence for the notion of, If the 2 genes were not linked, the hybrid AaBb, A hybrid with 2 pairs of linked genes can also, However, new recombinants (Ab and aB) will arise. Mutations are the original source of genetic variation. Major causes of variation include mutations, gene flow, and sexual reproduction.
