Genetic code and Gene pool
The sequence of bases in a gene and the amino acids in a proten. This relationship of nucleotide bases of a gene and the amino acids is known as the genetic code. Properties of genetic code: The Genetic code is triplet. The Genetic code is commaless. The Genetic code is universal. The Genetic code is degenerate. The Genetic code is Non overlapping. The Genetic code has polarity.
Total variety of genes and alleles present in a sexually reproducing population. In a population, there are many possible alleles for all genes. Thus, the gene pool is the total genetic make up of an entire population. Importance of gene pool: The gene pool helps us to know the total genetic make up of an entire population. According to Villie and Dethier, population is characterized by a certain gene pool. The genotype frequency is used in predicting possible outcomes of particular crosses. Allele ( gene) Frequency: A gene pool is characterized by frequency of given alleles expressed in a ratio or percent within a population. In a population, several forms of each gene may exist and these are called alleles.
