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.
1 Genotype: the genetic make up. 2  For example, homozygous dominant (TT), heterozygous (Tt), homozygous recessive (tt). 3  Gene: a gene is a stretch of DNA that codes for a trait. 4  In molecular biology, the gene codes for a protein, which acts to bring about a trait. For example, height, color, whether the organism exhibits a trait. 2  Genotype: the genetic make up. 3  For example, homozygous dominant (TT), heterozygous (Tt), homozygous recessive (tt). 4  Gene: a gene is a stretch of DNA that codes for a trait.
