The key difference between polygenic inheritance and pleiotropy is that in polygenic inheritance, one phenotypic trait is controlled by multiple genes, while in pleiotropy, one gene affects multiple unrelated phenotypic traits. Generally, one gene codes for one phenotypic trait. There are two alleles for one gene. The two alleles may be homozygous dominant (AA), homozygous […]
Difference Between Nullisomy and Double Monosomy
The key difference between nullisomy and double monosomy is that nullisomy is the loss of both pairs of homologous chromosomes while double monosomy is the loss of one chromosome from each of two pairs of homologous chromosomes. Euploidy and aneuploidy are two chromosomal variations identified in organisms. Aneuploidy refers to a variation in the total […]
Difference Between Symmetric and Asymmetric Karyotype
The key difference between symmetric and asymmetric karyotype is that symmetric karyotype shows a smaller difference between the smallest and largest chromosomes in the set while asymmetric karyotype shows a larger difference between the smallest and largest chromosomes in the set. A karyotype is a diagram which shows the correct number and structure of the […]
Difference Between Punnett Square and Pedigree
The key difference between Punnett square and pedigree is that Punnett square displays all possible genotypes that can be inherited from two parental genotypes while pedigree represents the family history of a particular trait, especially the inheritance of a gene. Punnett square and pedigree are two types of tools that help to determine the probability […]
Difference Between Silent and Neutral Mutation
The key difference between silent and neutral mutation is that silent mutation is a specific type of neutral mutation that does not have an observable effect on the organism’s phenotype while neutral mutation is a change in the DNA sequence that is neither beneficial nor harmful to the ability of an organism to survive and […]
Difference Between Coupling and Repulsion
The key difference between coupling and repulsion is that coupling refers to the linkage of two dominant or two recessive alleles while repulsion refers to the linkage of dominant alleles with recessive alleles. Based on his experiments, Gregor Mendel stated three laws of inheritance: the law of dominance, the law of segregation and the law […]
Difference Between Compound Heterozygote and Double Heterozygote
The key difference between compound heterozygote and double heterozygote is that compound heterozygote is an individual who has two different mutated alleles at a particular gene locus while double heterozygote is an individual who is heterozygous at two separate genetic loci. Generally, a gene has two alleles since organisms are diploid. Alleles are the variant […]
Difference Between Blending and Particulate Inheritance
The key difference between blending and particulate inheritance is that in blending inheritance, offspring is a blend of both parents, while in particulate inheritance, offspring is a combination of both parents. Genes are the basic units of inheritance. Offspring receives genes or substances of inheritance from their parents (mother and father). Blending inheritance and particulate […]
Difference Between UTR and Intron
The key difference between UTR and intron is that UTR is a non-coding nucleotide sequence which is included in the mature mRNA sequence while intron is a sequence that is not included in the mature mRNA molecule. UTR or untranslated region is a non-coding sequence which is found in the mRNA molecule. In each side […]
Difference Between Additive and Nonadditive Genetic Patterns
The key difference between additive and nonadditive genetic patterns is based on the effect that it created on the phenotype. In additive genetic patterns, both alleles contribute to the phenotype in measurable amounts, while in nonadditive genetic patterns, only one allele contributes to the phenotype through dominance or epistasis. Both additive and nonadditive genetic patterns […]
