Key Difference – Monosomy vs Trisomy Chromosomal nondisjunction causes abnormal chromosome numbers in daughter cells. It can occur during cell division in mitosis and meiosis. As a result of nondisjunction in meiosis, aneuploid individuals are developed after the fertilization. Aneuploidy is a mutation in which chromosomal number is abnormal. A normal diploid cell (2n) […]
Difference Between YAC and M13 Phage Vector
Key Difference – YAC vs M13 Phage Vector DNA cloning is an important process which enables the propagation of important DNA fragments of organisms. It requires joining of specific DNA with vector DNA to create recombinant DNA which transforms into the host organism. A vector is a DNA molecule which behaves as a vehicle to carry foreign […]
Difference Between Vertical and Horizontal Gene Transfer
Key Difference – Vertical vs Horizontal Gene Transfer Gene transfer refers to the process that transfer or exchange genetic material between organisms. DNA which bears functional genes are exchanged among organisms causing the change in their genomic composition. It can occur in two types named vertical gene transfer and horizontal gene transfer. Horizontal gene […]
Difference Between Test Cross and Backcross
The key difference between test cross and backcross is that the test cross is the cross that occurs between a dominant phenotype and a recessive phenotype while the backcross is the cross that occurs between generation F1 hybrid and one of the two parents. Understanding the difference between test cross and backcross is important in […]
Difference Between Mendel’s First and Second Law
The key difference between Mendel’s First and Second Law is that Mendel’s first law describes the segregation of the alleles of a given locus into separate gametes during gametogenesis while Mendel’s second law describes the independent transmission of alleles of genes into daughter cells without the influence of each other. Mendelian inheritance describes Mendel’s first […]
Difference Between Dominant and Recessive Alleles
The key difference between dominant and recessive alleles is that dominant alleles are the alleles that give the phenotype, masking over the other phenotype, while recessive alleles are the alleles that are suppressed by the dominant allele. Usually, a chromosome contains a number of genes, and they exist in specific places. If genes exist in […]
Difference Between Gene Mutation and Chromosome Mutation
The key difference between gene mutation and chromosome mutation is that the gene mutation causes alteration of the nucleotide sequence of a gene while the chromosome mutation causes a structural change of the segment of a chromosome including many genes. Mutations are the permanent alterations of the nucleotide sequences of the genetic material of organisms. […]
Difference Between Prokaryotic and Eukaryotic Genome
The key difference between prokaryotic and eukaryotic genome is that the prokaryotic genome is present in the cytoplasm while eukaryotic genome confines within the nucleus. Genome refers to the entire collection of DNA of an organism. In other words, the genome is the genetic material of an organism that contains the total genetic information. Most […]
Difference Between Allele and Genotype
The key difference between allele and genotype is that the allele is one of the variant forms of a gene located at the same genetic locus of a chromosome while genotype is the genetic constitution of a particular trait. Genetics is the study of genes and hereditary patterns in organisms. Chromosomes are the structures that […]
Difference Between Autosomes and Chromosomes
The key difference between autosomes and chromosomes is that humans have 22 pairs of autosomes that determine somatic characteristics while humans have a total of 23 pairs of chromosomes in a cell. As cell theory explains, a new cell originates from a pre-existing cell by cell division. Further studies have recognized the importance of the […]
