WebFeb 19, 2024 · For example, with a gene flow rate of 0.10 (10% of individuals are immigrants), divergence occurs more readily if two genes each experience a selection intensity of 0.20 each (20% difference in expected fitness, higher than the gene flow rate) than if 10 genes experience an intensity of 0.04 (weaker than gene flow). WebIn genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal-, and Robertsonian translocation. Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous …

This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations, as shown in Table 6.6.1.
WebIn molecular biology shorthand, the nitrogenous bases are often just referred to by their one-letter symbols, A, T, G, C, and U. DNA contains A, T, G, and C, while RNA contains A, U, G, and C (that is, U is swapped in for T). Sugars In addition to having slightly different sets of bases, DNA and RNA nucleotides also have slightly different sugars.
