Vertigo and disequilibrium may cause a feeling of dizziness, but those two terms describe different symptoms. Vertigo is characterized by a spinning sensation, like the room is moving. It may also feel like motion sickness or as if youâre leaning to one side. Disequilibrium is a loss of balance or equilibrium.
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive.For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.lso, an allele may be dominant for a particular aspect of phenotype but not for other aspects influenced by the same gene. Dominance differs from epistasis, a relationship in which an allele of one gene affects the expression of another allele at a different gene.
â¢ Incomplete dominance and codominance are types of inheritance of traits where both alleles are neither dominant nor recessive. â¢ In incomplete dominance, the resulting trait is a blend of the traits of parents whereas in codominance, both traits show up in the offspring.
