The key difference between unambiguous and degenerate code is that genetic code is an unambiguous code since a particular codon always codes for the same amino acid, while genetic code is a degenerate code since one amino acid may be specified by more than one codon. Genes are the structural units of heredity. There is […]
Difference Between Gene Conversion and Crossover
The key difference between gene conversion and crossover is that gene conversion involves the unidirectional transfer of genetic material from a donor sequence to an acceptor sequence, while crossover is the exchange of genetic material during the sexual reproduction between two homologous chromosomes’ nonsister chromatids. Gene conversion and crossover are two mechanisms of homologous recombination. […]
Difference Between Intragenic and Extragenic Suppressor Mutation
The key difference between intragenic and extragenic suppressor mutation is that intragenic suppressor mutation is a suppressor mutation that occurs within the same gene. In contrast, an extragenic suppressor mutation is a mutation which occurs in a different gene. A mutation is an alteration of the nucleotide sequence of a gene. Suppression mutation is a […]
Difference Between X Linked Dominant and X Linked Recessive
The key difference between X linked dominant and X linked recessive is that X linked dominant is a genetic disorder caused due to a dominant mutant gene located on the X chromosome while X linked recessive is a genetic disorder caused due to one or two recessive mutant genes located on the X chromosomes. X […]
Difference Between Trisomy 18 and 21
The key difference between trisomy 18 and 21 is that trisomy 18 is a chromosomal disorder caused due to the presence of an extra chromosome 18 while trisomy 21 is a chromosomal disorder caused due to the presence of an extra chromosome 21. A healthy human cell contains a total of 46 chromosomes (23 pairs). […]
Difference Between Reversion and Suppression Mutation
The key difference between reversion and suppression mutation is that reversion mutation is a mutation that precisely restores the wild type DNA sequence back while the suppression mutation is a second mutation at a distinct site which suppresses the phenotypic effect of the first mutation. A mutation is a change in a nucleotide sequence of […]
Difference Between Monogenic Disorders and Chromosomal Disorders
The key difference between monogenic disorders and chromosomal disorders is that monogenic disorders are disorders associated with single genes, while chromosomal disorders are diseases associated with abnormalities in chromosomes and part of the chromosomes. Gene is the structural and functional unit of heredity. Gene has a specific nucleotide sequence. There are thousands of genes in […]
Difference Between Conditional and Constitutive Knockout
The key difference between conditional and constitutive knockout is that conditional knockout is the deletion of a gene of interest from a specific tissue or organ while constitutive knockout is the permanent deletion of a gene of interest from the animal. Mouse is a good analogue for most human biological processes since they share about […]
Difference Between Random Orientation and Independent Assortment
The key difference between random orientation and independent assortment is that random orientation is the random line up of homologous chromosome pairs at the equator during the metaphase of meiosis 1 while independent assortment refers to the inheritance of genes independently from the inheritance of any other gene. Cell divisions make new vegetative cells or […]
Difference Between Multifactorial and Polygenic Traits
The key difference between multifactorial and polygenic traits is that multifactorial traits are traits that are controlled by many genes and environmental factors, while polygenic traits are traits that are controlled by more than one gene. Mendelian inheritance describes that inheritance of a trait is controlled by a single gene which has two alleles. Gregor […]
