An electromagnetic field (also EMF or EM field) is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction.
Individuals who have two copies of the same allele are said to be homozygous at that locus. Individuals who receive different alleles from each parent are said to be heterozygous at that locus. The alleles an individual has at a locus is called a genotype.he illustration explores the relationship between the presence of different alleles at a specific locus and an organism's genotype and phenotype. The organism in the model is a plant. It is diploid and the trait is flower color.
Remember, individuals must have two alleles for a gene, so someone could be homozygous dominant (EE), homozygous recessive (ee), or heterozygous (Ee). In this example, the recessive trait is having attached earlobes and is only seen in someone with the genotype ee (homozygous recessive).xamples of Recessive Traits. We know many examples of traits controlled by recessive alleles; however, as scientists are more thoroughly studying the genetics of traits, they are finding that many have multiple genes and alleles associated with them, instead of just one gene with two alleles as explained above.
