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 […]
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 […]
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 […]
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. […]
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 […]
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 […]
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 […]
The key difference between plasmid and chromosome is that the plasmid is a circular double-stranded extra-chromosomal DNA structure of bacteria while the chromosome is a well-organized thread-like structure that contains genomic DNA tightly coiled with proteins. The bacterial cell contains a chromosome and several extra-chromosomal DNA circles called plasmids. Bacterial chromosome contains the genomic DNA […]
The key difference between aneuploidy and polyploidy is that the aneuploidy is a condition that happens due to a missing or an extra chromosome in the genome of an organism while the polyploidy is a condition when a cell contains more than two sets of chromosomes. Every organism has a particular set of chromosomes in […]
The key difference between penetrance and expressivity is that the penetrance refers to the proportion of genotypes that actually show expected phenotypes in a population while the expressivity is the degree to which trait expression differs among individuals. Penetrance and expressivity are two terms very commonly used in genetic analysis. Though alleles are alternative forms […]
