Explain what is meant by the term phenotype
WebHeritability is expressed as H2 = Vg / Vp, where H is the heritability estimate, Vg the variation in genotype, and Vp the variation in phenotype. Heritability estimates range in value from 0 to 1. If H = 1, then all variation in a population is due to differences or variation between genotypes (i.e., there is no environmentally caused variation). WebDefinition. 1 / 20. Epigenetics is the study of changes in individuals, and in individual cells, caused by changes in gene expression that are unrelated to changes in the genetic code itself (nucleotide changes) It's a study of gene expression due to changes in chromatin structure resulting from the chemical modification of chromatin.
