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.
Advantages and Disadvantages of Asexual Reproduction. Asexual reproduction can be very advantageous to certain animals and protists. Organisms that remain in one particular place and are unable to look for mates would need to reproduce asexually. Another advantage of asexual reproduction is that numerous offspring can be produced without costing the parent a great amount of energy or time.
